------------------------------------------------------------------------------
This document details the changes between this version, bash-4.0-beta,
-and the previous version, bash-4.0-beta.
+and the previous version, bash-4.0-alpha.
1. Changes to Bash
- make sure the error messages printed when setlocale fails are
localizable
-builtins/shopt.def
- - include <readline/history.h> if history in use
- - new function, set_extglob, sets history_no_expand_chars to a
- value that includes `)' if extended globbing is enabled, so we
- don't try history expansion on !(...). Fixes bug reported by
- Yang Zhang <yanghatespam@gmail.com>
+ 1/11
+ ----
+lib/readline/histexpand.c
+ - make sure that every time history_no_expand_chars is tested, we
+ also call the history_inhibit_expansion_function if it's set.
+ Fixes bug reported by Yang Zhang <yanghatespam@gmail.com>
+
+ 1/12
+ ----
+trap.c
+ - make sure to call parse_and_execute with the SEVAL_RESETLINE bit
+ set in the flags so it will reset the line number when running
+ the trap commands. Partial fix for bug reported by
+ peter360@fastmail.us
+
+ 1/14
+ ----
+builtins/reserved.def
+ - document `coproc' so it can be used with `help' builtin. Pointed
+ out by Pierre Gaston <pgas@freeshell.org>
+
+lib/sh/casemod.c
+ - added two new flags: CASE_UPFIRST and CASE_LOWFIRST to casemod
+ the first character of the passed string and pass the rest
+ through unchanged. Fixes bug reported by Jan Schampera
+ <jan.schampera@web.de>
+
+externs.h
+ - new defines for CASE_UPFIRST and CASE_LOWFIRST
+
+subst.c
+ - use CASE_UPFIRST for ^ and CASE_LOWFIRST for , casemod operators
+
+builtins/mapfile.def
+ - call zreset() before calling first zgetline(), to clean out any
+ remaining data in local buffer used by zreadc. Fixes bug
+ reported by Pierre Gaston <pierre.gaston@gmail.com>
+
+ 1/15
+ ----
+lib/sh/zread.c
+ - renamed zreadintr to zreadretry -- not perfect, but better
+ - new functions: zreadintr, which just calls read so it can be
+ interruptible, and zreadcintr, which is like zreadc but uses
+ zreadintr to fill the buffer
+
+lib/sh/zgetline.c
+ - in zgetline, when zread/zreadc return <= 0, make sure line is
+ non-null before assigning to line[nr]
+
+builtins/mapfile.def
+ - return an error right away if the supplied array variable name
+ refers to a readonly or noassign array
+ - set interrupt_immediately so calls to zgetline can be
+ interrupted. Fixes bug reported by Pierre Gaston
+ <pierre.gaston@gmail.com>
+ - if interactive, pass the SEVAL_INTERACT and SEVAL_NOHIST flags
+ to parse_and_execute when calling callbacks. Fixes bug reported
+ by Pierre Gaston <pierre.gaston@gmail.com>
+ - add `readarray' as a synonym for mapfile
+
+doc/{bash.1,bashref.texi}
+ - document behavior of mapfile builtin adding index of array element
+ to be assigned as additional argument to callback string. Reported
+ by Pierre Gaston <pierre.gaston@gmail.com>
+ - document readarray as synonym for mapfile
+
+builtins/common.c
+ - new error function, sh_ttyerror(set), prints an error message having
+ to do with setting or getting terminal attributes
+
+builtins/read.def
+ - print error message if read fails to set terminal attributes
+
+ 1/16
+ ----
+execute_cmd.c
+ - new function, coproc_reap, calls coproc_dispose if sh_coproc is
+ marked as COPROC_DEAD
+ - new function, cpl_reap, disposes coprocs marked as COPROC_DEAD
+ from coproc list
+ - change coproc_pidchk to just mark the coproc as dead instead of
+ calling coproc_dispose, so we don't call unsafe functions from
+ a signal handler. Fixes bug reported by Andreas Schwab
+ <schwab@suse.de>
+
+execute_cmd.h
+ - new extern declaration for coproc_reap
+
+command.h
+ - new flags for c_flags member of a struct coproc
+
+{jobs,nojobs}.c
+ - add call to coproc_reap in cleanup_dead_jobs, which will do the
+ right queueing or blocking of SIGCHLD
+
+trap.c
+ - modify change from 1/12 to not reset the line number when running
+ the DEBUG and RETURN traps
+
+ 1/18
+ ----
+lib/sh/casemod.c
+ - change default operations to work on entire passed string instead
+ of breaking into words at non-alpha-numerics. Use new
+ CASE_USEWORDS flag to enable by-word behavior. Fixes bug reported
+ by Jan Schampera <jan.schampera@web.de>
+
+builtins/printf.def
+ - in vbprintf, bracket each call to vsnprintf (which uses the args
+ passed to vbprintf) with SH_VA_START and va_end, so we can
+ reninitialize the argument list for each call. This is actually
+ what the C standard requires. Fixes bug that caused printf -b
+ to `ignore' first % format specifier if it came first in the
+ string. Reported by David Leverton <levertond@googlemail.com>
+
+builtins/mapfile.def
+ - start the line count at 1, since it doesn't get incremented before
+ (or after) reading the first line, so things like
+ `mapfile -n 5 -c 1 -C 'echo foo' array < file' work right and call
+ the callback after the first line is read. Fixes bug reported by
+ Pierre Gaston <pierre.gaston@gmail.com>
- make sure the error messages printed when setlocale fails are
localizable
-builtins/shopt.def
- - include <readline/history.h> if history in use
+ 1/11
+ ----
+lib/readline/histexpand.c
+ - make sure that every time history_no_expand_chars is tested, we
+ also call the history_inhibit_expansion_function if it's set.

- ----
-subst.c
- - new function, mbstrlen(s), returns length of a multibyte character
- string
-
-include/shmbutil.h
- - new macro, MB_STRLEN(s), calls mbstrlen or STRLEN as appropriate

- 8/1
- ---

- - describe_pid needs to write to stderr, not stdout (POSIX)
- - start_job, since it's only used by builtins (fg/bg), needs to write
- its output to stdout, not stderr (POSIX)
-

- found
-
-builtins/hash.def
- - `hash' should print its `hash table empty' message to stderr
-
-lib/readline/misc.c
- - back out 7/7 change to _rl_maybe_save_line; it breaks emacs-mode ^P
-
-general.c
- - changed base_pathname so that it will return reasonable results for
- non-absolute pathnames -- this is what is intended by all of its

- the current locale
-
- 8/2

- is unset. Fix from William Park
-
-lib/readline/display.c

-
-variables.c

- to be configured --without-gnu-malloc
-
-lib/readline/vi_mode.c
- - in rl_vi_search, free any saved history line before starting the
- search, so failure leaves you at that line, not the last line in

- - change BASH_CHECK_DEV_FD to make sure that file descriptors > 2 are
- accessible via /dev/fd, unlike FreeBSD 5.x
-
-lib/sh/strftime.c
- - make sure `zone' is initialized with gettimeofday before it is used
- - work around HPUX lack of `altzone' and differing definitions of
- `timezone'
-
-lib/malloc/malloc.c
- - internal_memalign and memalign now take a `size_t' as their first
- argument, which seems to be the prevailing standard
-
-lib/malloc/{malloc.c,shmalloc.h}
- - change sh_memalign to take a `size_t' as its first argument
-
-builtins/echo.def
- - if posixly_correct and xpg_echo are both set, don't try to interpret

- Eggert)
-
-doc/bashref.texi
- - amend description of bash posix mode to include new echo behavior
-
-builtins/fg_bg.def
- - allow bg to take multiple job arguments, as posix seems to specify,
- placing them all in the background, returning the status of the last
- one as the status of `bg'
-
-lib/readline/vi_mode
- - fix _rl_vi_change_mbchar_case (multibyte-char version of `~'
- command) to have the right behavior at EOL -- handle case where vi
- mode backs up at the end of the line
-
- 8/18
- ----
-array.c
- - check for an empty array in array_rshift before shifting elements
- and adjusting max_index
- - check for null array in array_subrange
-
-jobs.c
- - fix raw_job_exit_status to not ignore exit status of the last

-
- 8/19
- ----
-lib/readline/mbutil.c
- - make sure _rl_find_next_mbchar_internal has a valid multibyte
- character before it checks whether or not it's a zero-width
- wide character and adjusts point accordingly
-
- 8/24
- ----
-bashline.c
- - new function, bash_directory_expansion, duplicates the expansions
- performed on the directory name by rl_filename_completion_function
- - call bash_directory_expansion in command_word_completion_function
- if we decide we're doing tilde expansion (and any other
- canonicalization) on the directory name being completed
-
- 8/25
- ----
-configure.in
- - use new-style AC_CHECK_HEADER to check for sys/ptem.h (which requires
- sys/stream.h). The correct checks are in the code, but autoconf
- complains if sys/stream.h is not included, rather than simply
- checking for the header's presence
-
- 8/26
- ----
-builtins/hash.def
- - fix a bug that prevented `hash -d' from working right (as soon as
- hash removed a command from the table, the bug caused it to be added
- right back)
-
- 8/27
- ----
-doc/{bash.1,bashref.texi}
- - explicitly note that conditional primaries that operate on files
- operate on the targets of symbolic links rather than the links
- themselves
-
- 8/30
- ----
-lib/readline/display.c
- - fix multibyte calculation of `physchars' in prompt expansion, to
- handle double-width multibyte characters correctly

- Tomohiro Kubota
-
- 9/6
- ---
-subst.c
- - change word_list_split to avoid really bad behavior caused by calling
- list_append for each split word -- as the list gets long, you have
- to traverse it every time. Keep a pointer to the end of the list and
- and just tack onto it
-
- 9/8
- ---
-lib/readline/complete.c
- - change fnprint to calculate the displayed width of a filename in
- the same way as fnwidth
-
-subst.c
- - in verify_substring_values, when expanding ${array[@]:offset}, make
- sure negative offsets count from one greater than the array's
- maximum index so things like ${x[@}: -1} work to give the last element
- (requires fixing array tests)
-
-builtins/common.c
- - new error function, sh_wrerror(), for builtins to call when a write
- error occurs
-
-builtins/common.h
- - extern declaration for sh_wrerror()
-

-
-builtins/echo.def
- - report write errors with sh_wrerror() instead of just returning
- failure
-
-builtins/printf.def

- rather than void
- - report write errors when printstr() fails, return failure
- - if any of the PF/printf calls fail, report write error and return
- failure
-
-execute_cmd.c
- - change execute_in_subshell so the subshell command inherits the
- command timing flags from the enclosing COMMAND *
-

-
- 9/13
- ----
-variables.c
- - make BASH_ARGC, BASH_ARGV, BASH_LINENO, and BASH_SOURCE

- in a case statement could have a semicolon added after it, if the
- `case word' was on a previous line
-

-
- 9/18
- ----
-lib/sh/shquote.c
- - don't quote CTLESC and CTLNUL with CTLESC in sh_backslash_quote, as

- directory name
-
-bashline.c
- - experimental change to suppress appending a slash for a completed
- filename that is found in PATH as well as a directory in the current
- directory under certain circumstances: a single instance found in
- $PATH when `.' is not in $PATH, and multiple instances found in the
- $PATH, even when `.' is in the $PATH
-
- 9/24
- ----
-command.h
- - new word flag: W_ASSIGNRHS, means word is rhs of assignment statement
- - new word flag: W_NOTILDE, means word is not to be tilde expanded
- - new word flag (internal): W_ITILDE, means the next character is a

-
-general.c
- - new set of tilde suffixes for use when parsing the RHS of an
- assignment statement and =~ should not be subject to tilde expansion
- - if ASSIGN_P argument to bash_tilde_expand is 2, use tilde prefixes

- - new function bash_tilde_find_word, drop-in replacement for
- tilde_find_word
-
-subst.c
- - call bash_tilde_expand with secord argument of 2 when expanding rhs
- of an assignment statement, so tildes after second and subsequent
- `=' in an assignment are not expanded
- - new function, expand_string_assignment, to expand the rhs of an
- assignment statement
- - add `~' to EXP_CHAR, the characters that will cause the word
- expansion functions to be called
- - move tilde expansion into expand_word_internal instead of many
- different calls to bash_tilde_expand scattered across different
- functions. NOTE: This means that double quotes surrounding a
- {paramOPword} expansion will cause tilde expansion to NOT be
- performed on `word'. I think this is right, what POSIX specifies,
- and consistent with the behavior of other characters in the rhs
-
-execute_cmd.c
- - take out calls to bash_tilde_expand before calling word expansion
- functions

- - set W_ASSIGNARG flag in fix_assignment_words if necessary
-
-subst.c
- - new function, do_compound_assignment, encapsulates the necessary
- code to perform a compound array assignment (including creation of
- local variables); called from do_assignment_internal
- - to fix the double-expansion problem with compound array assignments
- that are arguments to builtins like `declare', changed
- shell_expand_word_list to treat those arguments like assignment
- statements (with proper creation of local variables inside shell
- functions) and pass the attribute-setting portion of the statement
- onto the builtin. This is what ksh93 appears to do, from inspection
- of the `ksh93 -x' output
-
-execute_cmd.c
- - fix execute_simple_command: in case of pipeline or async command,
- when forking early, set `subshell_environment' so that it can contain
- both SUBSHELL_PIPE and SUBSHELL_ASYNC -- the two should not be
- mutually exclusive. Fixes bug reported by pierre.humblet@ieee.org
- - remove references to last_pid, old_command_subst_pid; use NO_PID as
- a sentinel value to decide whether or not a child process has been
- created and needs to be waited for. Submitted by
- pierre.humblet@ieee.org to fix recycling-pid problem on cygwin
-
-doc/{bash.1,bashref.texi}

- export attribute set (which they all do -- something to look at) and
- the `propagate' attribute set to be propagated down to the next
- scope
-
-execute_cmd.c
- - change execute_builtin so that if CMD_COMMAND_BUILTIN is set in the
- passed flags argument, call pop_scope with a value that says the
- builtin is not special, since `command' means that preceding variable
- assignments don't persist in the environment. Fixes problem with
- variable assignments preceding command preceding special builtin
- keeping those variable assignments around (when in posix mode)
-
- 10/20

-variables.c
- - new special variable hook function for COMP_WORDBREAKS; sets

- being appended to, use make_variable_value to create the new
- value
- - change bind_variable_internal to understand dynamic variables with
- assign_function set, and handle them the same way
- - RANDOM and LINENO now get the integer attribute, so appending works
- as expected
- - ditto for HISTCMD, MAILCHECK, OPTIND
-
-lib/readline/display.c
- - change _rl_make_prompt_for_search to set prompt_physical_chars

- - change rl_restore_prompt to set the `save' variables back to
- NULL/0 so code can check whether or not the prompt has been saved
- - change rl_message and rl_clear_message to save and restore the
- prompt if the caller has not already done it (using a simple
- semaphore-like variable)
- - change rl_message to call expand_prompt, so that local_prompt and
- local_prompt prefix are set before calling the redisplay functions,
- in case the prompt is longer than a screenwidth (fixes bug
- reported to debian by epl@unimelb.edu.au)
-
-lib/readline/doc/rltech.texi
- - make sure to note that rl_save_prompt should be called before
- rl_message, and rl_restore_prompt before rl_clear_message
-
-pcomplete.c

- execute_shell_function in gen_shell_function_matches. Fixes bug

-
-lib/readline/readline.c
- - fix _rl_dispatch_subseq in the case where we're recursing back up
- the chain (r == -2) and we encounter a key shadowed by a keymap,
- but originally bound to self-insert. Calling rl_dispatch with
- ANYOTHERKEY as the first argument will call rl_insert, but with

- after redoing `i' or `a'
-
-jobs.c
- - new function, delete_old_job (pid), checks whether or not PID is in
- a job in the jobs list. If so, and the job is dead, it just removes
- the job from the list. If so, and the job is not dead, it zeros
- the pid in the appropriate PROCESS so pid aliasing doesn't occur

- wrapped around. Finally fixes the bug reported by Tim Waugh

-
-jobs.c
- - in wait_for, if the original SIGINT handler is SIG_IGN, don't set

- <stephane_chazelas@yahoo.fr>
-
-lib/readline/signals.c
- - new variables to keep track of special characters corresponding to
- SIGINT, SIGQUIT, and SIGTSTP
- - new variable to keep track of whether tty is echoing control
- characters corresponding to SIGINT, SIGQUIT, and SIGTSTP
- - new function, _rl_echo_signal_char(int sig) to display the tty
- special char generating SIGINT, SIGQUIT, or SIGTSTP. Based on
- idea and code from Joe Peterson <joe@skyrush.com>
- - call rl_echo_signal_char in rl_signal_handler: if the terminal
- settings indicate it, readline will echo characters that generate
- keyboard signals
-
-lib/readline/rltty.c
- - set _rl_intr_char, _rl_quit_char, and _rl_susp_char to special
- characters that generate signals from keyboard
- - set _rl_echoctl if ECHOCTL tty flag is set
-
-lib/readline/rlprivate.h
- - extern declarations for _rl_intr_char, _rl_quit_char, and
- _rl_susp_char
- - extern declaration for _rl_echoctl
-
-lib/readline/readline.h
- - extern declaration for rl_echo_signal_char()
-
-lib/readline/doc/rltech.texi
- - document rl_echo_signal_handler(): available for applications
- that install their own signal handlers

-execute_cmd.c
- - fix errexit logic to not cause the shell to exit when a command in
- a pipeline fails. Fixes bug reported by Marcin Owsiany
- <marcin@owsiany.pl>
-
- 10/14
- -----
-builtins/evalstring.c
- - don't short-circuit execution in parse_and_execute if we want to
- run an exit trap. Fixes bug reported by Steffen Kiess
- <s-kiess@web.de>
-
- 10/18
- -----
-parse.y
- - fix error production to only call YYACCEPT if the shell is currently
- interactive and not in parse_and_execute (so parser errors in
- things like eval will correctly set $?). Fixes bug reported by
- marco-oweber@gmx.de
-
-execute_cmd.c
- - make sure variable name errors in execute_for_command and non-
- identifier function names in execute_intern_function set the
- return status to EX_BADUSAGE (2), not EX_USAGE (258)
-
-parser.h
- - new parser state, PST_REPARSE
-
-parse.y
- - turn PST_REPARSE on in parse_string_to_word_list
- - in parse_matched_pair, if parsing a single-quoted string and
- PST_REPARSE is set, don't requote CTLESC or CTLNUL. Fixes bug with
- compound array assignment using $'\x7f' reported by Antonio Macchi
- <antonio_macchi@alice.it>
-

-configure.in
- - define LOCAL_LDFLAGS as `-z interpose' on Solaris 8, 9, and 10 to
- allow the bash malloc to interpose the libc malloc when called by
- library functions pre-bound to the libc malloc. Suggested by
- Serge Dussud <Serge.Dussud@Sun.COM>

-doc/bash.1
- - add single-sentence descriptions to rest of parameter expansions.
- Suggested by Ken Irving <fnkci@uaf.edu>
-
- 10/27
- -----
-subst.c
- - rearrange code in skip_to_delims to allow quote characters and other
- shell expansion characters to be delimiters
- - add new flags value for inverting search: skip to the next character
- NOT in the set of delimiters passed as an argument
-
-subst.h
- - define for new SD_INVERT flag value for skip_to_delims
-
- 10/28
- -----
-bashline.c
- - new bindable functions: shell-forward-word and shell-backward-word.
- Like forward-word and backward-word, but understand shell quoting
- and use shell metacharacters and whitespace as delimiters.
- Suggested by Andre Majorel <amajorel@teaser.fr>
- - new bindable functions: shell-kill-word and shell-backward-kill-word.
- Like kill-word and backward-kill-word, but understand shell quoting
- and use shell metacharacters and whitespace as delimiters.
- Suggested by Andre Majorel <amajorel@teaser.fr>
-

-redir.c
- - add extra argument to add_undo_redirect: fdbase. FD used to save
- a file descriptor must be > fdbase if fdbase >= SHELL_FD_BASE. A
- value of -1 for fdbase means to just use SHELL_FD_BASE. Fixes bug
- with 0<&10 reported by Clark Jian Wang <dearvoid@gmail.com>
-
- 11/5
- ----
-unwind_prot.c
- - new function: have_unwind_protects(); returns 1 if unwind_protect_list
- is not empty
-
-unwind_prot.h
- - extern declaration for have_unwind_protects
-
-builtins/evalstring.c
- - in parse_and_execute_cleanup, make sure that we don't call
- run_unwind_frame and expect it to decrement parse_and_execute_level
- if there's no unwind_protect_list, since there's a while loop in
- throw_to_top_level that calls parse_and_execute_cleanup as long as
- parse_and_execute_level is non-zero
-
- 11/9
- ----
-variables.c
- - fix the assign function for COMP_WORDBREAKS to allocate new memory
- to store as the variable's value, to avoid freeing memory twice
- if the variable is unset after rl_completer_word_break_characters
- is freed and reallocated. Fix from Mike Stroyan <mike@stroyan.net
-
- 11/11
- -----
-bashline.c
- - new function to reset the value of rl_completer_word_break_characters
- while honoring setting of `hostcomplete': reset_completer_word_break_chars.
-
-bashline.h
- - new extern declaration for reset_completer_word_break_chars.
-
-variables.c
- - call reset_completer_word_break_chars in sv_comp_wordbreaks when the
- variable is unset
-
-[bash-4.0-beta frozen]
-
- 11/16
- -----
-subst.c
- - call set_pipestatus_from_exit in exp_jump_to_top_level so that
- failed expansions that set $? will set $PIPESTATUS. Fixes bug
- reported by Eric Blake <ebb9@byu.net>
-
- 11/20
- -----
-general.c
- - new 'file_exists(fn)' primitive; just calls stat(2)
-
-general.h
- - new extern declaration for file_exists
-
-bashline.c
- - add `~' to rl_filename_quote_characters so make_quoted_replacement
- will call bash_quote_filename for words containing `~'. Then
- bash_quote_filename can make choices based on that
- - change quote_word_break_chars to backslash-quote the tilde in a
- filename with a leading tilde that exists in the current directory,
- since we want to inhibit tilde expansion in this case
-
-execute_cmd.c
- - call file_isdir from shell_execve instead of stat(2) directly
-
-bashhist.c
- - use file_exists and file_isdir primitives instead of calling stat
-
- 11/21
- -----
-redir.c
- - When undoing saving of non-standard file descriptors (>=3) using
- file descriptors >= SHELL_FD_BASE, we set the saving fd to be
- close-on-exec and use a flag (RX_SAVCLEXEC) to decide how to set
- close-on-exec when the fd is restored. Set flag in add_undo_redirect,
- check in do_redirection_internal. Fixes problem reported by Andreas
- Schwab <schwab@suse.de>
-
- 11/26
- -----
-subst.c
- - fix param_expand to have expansions of $@ and $* exit the shell if
- there are no positional parameters and `set -u' is enabled. Fixes
- bug reported by Dan Jacobson <jidanni@jidanni.org>
-
- 11/27
- -----
-lib/readline/display.c
- - fix update_line to not call space_to_eol if current cursor position
- (_rl_last_c_pos) indicates that we're already at end of line.
- Partial fix for bug reported by Mike Frysinger <vapier@gentoo.org>
- - in update_line, don't call insert_some_chars if that will start
- before the last invisible character in the prompt string and not
- draw the entire prompt string. More of the partial fix for bug
- reported by Mike Frysinger <vapier@gentoo.org>
- - fix update_line to adjust _rl_last_c_pos by wrap_offset when adding
- characters beginning before the last invisible character in the
- prompt. New code is same as previously existed in a different code
- path. Rest of fix for bug from Mike Frysinger <vapier@gentoo.org>
- - fix assignment of newline breaks (inv_lbreaks) to correctly account
- for prompts longer than two screen lines containing invisible
- characters. The assumption is that part of the invisible characters
- are on the first line (prompt_invis_chars_first_line) and the
- remainder are on the last (wrap_offset - prompt_invis_chars_first_line).
- Fix is in rl_redisplay. part of fix for bug reported by
- "Wesley J. Landaker" <wjl@icecavern.net> in
- http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=265182
- [TENTATIVE]
- - fix _rl_move_cursor_relative to correctly offset `dpos' by `woff'
- when there are invisible characters on lines after the second by
- using (_rl_screenwidth*_rl_last_v_pos) when seeing whether or not
- we just wrote some invisible characters. Rest of fix for bug
- reported in http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=265182
- [TENTATIVE]
-

- -----
-sig.c
- - reset the execution context before running the exit trap in
- termsig_handler
-
-general.c
- - set and unset terminate_immediately like interrupt_immediately in
- bash_tilde_expand
-
-builtins/read.def
- - change terminate_immediately to a counter instead of a flag, as
- interrupt_immediately is used
-
-lib/readline/display.c
- - slight change to fix from 11/27 to deal with prompts longer than a
- screen line where the invisible characters all appear after the
- line wrap. Fixes bug reported by Andreas Schwab <schwab@suse.de>
-
-builtins/{echo,printf}.def
- - increment terminate_immediately at entry; decrement before returning.
- Fix for bug reported by Ralf.Wildenhues@gmx.de

-
-{execute_cmd,sig,builtins/evalstring}.c
- - sentinel variable to keep track of whether or not we're supposed to
- ignore the failure status of a command executed in a command
- substitution even if the `-e' option is set: comsub_ignore_return
- - increment and decrement comsub_ignore_return in execute_simple_command
- before calling expand_words
- - in parse_and_execute, if comsub_ignore_return is non-zero and the
- SUBSHELL_COMSUB bit is set in subshell_environment, enable the
- CMD_IGNORE_RETURN flag in every command executed from the passed
- string. Fixes problem reported by Freddy Vulto <fvulto@gmail.com>
- - make sure to reset comsub_ignore_return every time we throw to the
- top level, like executing_list flag
-

-% @multitable macros
-% Amy Hendrickson, 8/18/94, 3/6/96
-%
-% @multitable ... @end multitable will make as many columns as desired.
-% Contents of each column will wrap at width given in preamble. Width
-% can be specified either with sample text given in a template line,
-% or in percent of \hsize, the current width of text on page.
-
-% Table can continue over pages but will only break between lines.
-
-% To make preamble:
-%
-% Either define widths of columns in terms of percent of \hsize:
-% @multitable @columnfractions .25 .3 .45
-% @item ...
-%
-% Numbers following @columnfractions are the percent of the total
-% current hsize to be used for each column. You may use as many
-% columns as desired.
-
-
-% Or use a template:
-% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-% @item ...
-% using the widest term desired in each column.
-%
-% For those who want to use more than one line's worth of words in
-% the preamble, break the line within one argument and it
-% will parse correctly, i.e.,
-%
-% @multitable {Column 1 template} {Column 2 template} {Column 3
-% template}
-% Not:
-% @multitable {Column 1 template} {Column 2 template}
-% {Column 3 template}
-
-% Each new table line starts with @item, each subsequent new column
-% starts with @tab. Empty columns may be produced by supplying @tab's
-% with nothing between them for as many times as empty columns are needed,
-% ie, @tab@tab@tab will produce two empty columns.
-
-% @item, @tab, @multitable or @end multitable do not need to be on their
-% own lines, but it will not hurt if they are.
-
-% Sample multitable:
-
-% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-% @item first col stuff @tab second col stuff @tab third col
-% @item
-% first col stuff
-% @tab
-% second col stuff
-% @tab
-% third col
-% @item first col stuff @tab second col stuff
-% @tab Many paragraphs of text may be used in any column.
-%
-% They will wrap at the width determined by the template.
-% @item@tab@tab This will be in third column.
-% @end multitable
-
-% Default dimensions may be reset by user.
-% @multitableparskip is vertical space between paragraphs in table.
-% @multitableparindent is paragraph indent in table.
-% @multitablecolmargin is horizontal space to be left between columns.
-% @multitablelinespace is space to leave between table items, baseline
-% to baseline.
-% 0pt means it depends on current normal line spacing.

- GNU GENERAL PUBLIC LICENSE
- Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The GNU General Public License is a free, copyleft license for
-software and other kinds of works.
-
- The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works. By contrast,
-the GNU General Public License is intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users. We, the Free Software Foundation, use the
-GNU General Public License for most of our software; it applies also to
-any other work released this way by its authors. You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
- To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights. Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received. You must make sure that they, too, receive
-or can get the source code. And you must show them these terms so they
-know their rights.
-
- Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
-
- For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software. For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
- Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so. This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software. The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable. Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products. If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
- Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary. To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- TERMS AND CONDITIONS
-
- 0. Definitions.
-
- "This License" refers to version 3 of the GNU General Public License.
-
- "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
- "The Program" refers to any copyrightable work licensed under this
-License. Each licensee is addressed as "you". "Licensees" and
-"recipients" may be individuals or organizations.
-
- To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy. The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
- A "covered work" means either the unmodified Program or a work based
-on the Program.
-
- To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy. Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
- To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies. Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
- An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License. If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
- 1. Source Code.
-
- The "source code" for a work means the preferred form of the work
-for making modifications to it. "Object code" means any non-source
-form of a work.
-
- A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
- The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form. A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
- The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities. However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work. For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
- The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
- The Corresponding Source for a work in source code form is that
-same work.
-
- 2. Basic Permissions.
-
- All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met. This License explicitly affirms your unlimited
-permission to run the unmodified Program. The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work. This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
- You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force. You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright. Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
- Conveying under any other circumstances is permitted solely under
-the conditions stated below. Sublicensing is not allowed; section 10
-makes it unnecessary.
-
- 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
- No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
- When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
- 4. Conveying Verbatim Copies.
-
- You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
- You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
- 5. Conveying Modified Source Versions.
-
- You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
- a) The work must carry prominent notices stating that you modified
- it, and giving a relevant date.
-
- b) The work must carry prominent notices stating that it is
- released under this License and any conditions added under section
- 7. This requirement modifies the requirement in section 4 to
- "keep intact all notices".
-
- c) You must license the entire work, as a whole, under this
- License to anyone who comes into possession of a copy. This
- License will therefore apply, along with any applicable section 7
- additional terms, to the whole of the work, and all its parts,
- regardless of how they are packaged. This License gives no
- permission to license the work in any other way, but it does not
- invalidate such permission if you have separately received it.
-
- d) If the work has interactive user interfaces, each must display
- Appropriate Legal Notices; however, if the Program has interactive
- interfaces that do not display Appropriate Legal Notices, your
- work need not make them do so.
-
- A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit. Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
- 6. Conveying Non-Source Forms.
-
- You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
- a) Convey the object code in, or embodied in, a physical product
- (including a physical distribution medium), accompanied by the
- Corresponding Source fixed on a durable physical medium
- customarily used for software interchange.
-
- b) Convey the object code in, or embodied in, a physical product
- (including a physical distribution medium), accompanied by a
- written offer, valid for at least three years and valid for as
- long as you offer spare parts or customer support for that product
- model, to give anyone who possesses the object code either (1) a
- copy of the Corresponding Source for all the software in the
- product that is covered by this License, on a durable physical
- medium customarily used for software interchange, for a price no
- more than your reasonable cost of physically performing this
- conveying of source, or (2) access to copy the
- Corresponding Source from a network server at no charge.
-
- c) Convey individual copies of the object code with a copy of the
- written offer to provide the Corresponding Source. This
- alternative is allowed only occasionally and noncommercially, and
- only if you received the object code with such an offer, in accord
- with subsection 6b.
-
- d) Convey the object code by offering access from a designated
- place (gratis or for a charge), and offer equivalent access to the
- Corresponding Source in the same way through the same place at no
- further charge. You need not require recipients to copy the
- Corresponding Source along with the object code. If the place to
- copy the object code is a network server, the Corresponding Source
- may be on a different server (operated by you or a third party)
- that supports equivalent copying facilities, provided you maintain
- clear directions next to the object code saying where to find the
- Corresponding Source. Regardless of what server hosts the
- Corresponding Source, you remain obligated to ensure that it is
- available for as long as needed to satisfy these requirements.
-
- e) Convey the object code using peer-to-peer transmission, provided
- you inform other peers where the object code and Corresponding
- Source of the work are being offered to the general public at no
- charge under subsection 6d.
-
- A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
- A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling. In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage. For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product. A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
- "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source. The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
- If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information. But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
- The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed. Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
- Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
- 7. Additional Terms.
-
- "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law. If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
- When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it. (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.) You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
- Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
- a) Disclaiming warranty or limiting liability differently from the
- terms of sections 15 and 16 of this License; or
-
- b) Requiring preservation of specified reasonable legal notices or
- author attributions in that material or in the Appropriate Legal
- Notices displayed by works containing it; or
-
- c) Prohibiting misrepresentation of the origin of that material, or
- requiring that modified versions of such material be marked in
- reasonable ways as different from the original version; or
-
- d) Limiting the use for publicity purposes of names of licensors or
- authors of the material; or
-
- e) Declining to grant rights under trademark law for use of some
- trade names, trademarks, or service marks; or
-
- f) Requiring indemnification of licensors and authors of that
- material by anyone who conveys the material (or modified versions of
- it) with contractual assumptions of liability to the recipient, for
- any liability that these contractual assumptions directly impose on
- those licensors and authors.
-
- All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10. If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term. If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
- If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
- Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
- 8. Termination.
-
- You may not propagate or modify a covered work except as expressly
-provided under this License. Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
- However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
- Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
- Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License. If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
- 9. Acceptance Not Required for Having Copies.
-
- You are not required to accept this License in order to receive or
-run a copy of the Program. Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance. However,
-nothing other than this License grants you permission to propagate or
-modify any covered work. These actions infringe copyright if you do
-not accept this License. Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
- 10. Automatic Licensing of Downstream Recipients.
-
- Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License. You are not responsible
-for enforcing compliance by third parties with this License.
-
- An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations. If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
- You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License. For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
- 11. Patents.
-
- A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based. The
-work thus licensed is called the contributor's "contributor version".
-
- A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version. For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
- Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
- In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement). To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
- If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients. "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
- If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
- A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License. You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
- Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
- 12. No Surrender of Others' Freedom.
-
- If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all. For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
- 13. Use with the GNU Affero General Public License.
-
- Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU Affero General Public License into a single
-combined work, and to convey the resulting work. The terms of this
-License will continue to apply to the part which is the covered work,
-but the special requirements of the GNU Affero General Public License,
-section 13, concerning interaction through a network will apply to the
-combination as such.
-
- 14. Revised Versions of this License.
-
- The Free Software Foundation may publish revised and/or new versions of
-the GNU General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
- Each version is given a distinguishing version number. If the
-Program specifies that a certain numbered version of the GNU General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation. If the Program does not specify a version number of the
-GNU General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
- If the Program specifies that a proxy can decide which future
-versions of the GNU General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
- Later license versions may give you additional or different
-permissions. However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
- 15. Disclaimer of Warranty.
-
- THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
- 16. Limitation of Liability.
-
- IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
- 17. Interpretation of Sections 15 and 16.
-
- If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
- END OF TERMS AND CONDITIONS
-
- How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) <year> <name of author>
-
- This program is free software: you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation, either version 3 of the License, or
- (at your option) any later version.
-
- This program is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License
- along with this program. If not, see <http://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
- If the program does terminal interaction, make it output a short
-notice like this when it starts in an interactive mode:
-
- <program> Copyright (C) <year> <name of author>
- This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License. Of course, your program's commands
-might be different; for a GUI interface, you would use an "about box".
-
- You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU GPL, see
-<http://www.gnu.org/licenses/>.
-
- The GNU General Public License does not permit incorporating your program
-into proprietary programs. If your program is a subroutine library, you
-may consider it more useful to permit linking proprietary applications with
-the library. If this is what you want to do, use the GNU Lesser General
-Public License instead of this License. But first, please read
-<http://www.gnu.org/philosophy/why-not-lgpl.html>.

-@c hence no sectioning command or @node.
-
-@display
-Copyright @copyright{} 2000,2001,2002 Free Software Foundation, Inc.

-
-Everyone is permitted to copy and distribute verbatim copies
-of this license document, but changing it is not allowed.
-@end display
-
-@enumerate 0
-@item
-PREAMBLE
-
-The purpose of this License is to make a manual, textbook, or other
-functional and useful document @dfn{free} in the sense of freedom: to
-assure everyone the effective freedom to copy and redistribute it,
-with or without modifying it, either commercially or noncommercially.
-Secondarily, this License preserves for the author and publisher a way
-to get credit for their work, while not being considered responsible
-for modifications made by others.
-
-This License is a kind of ``copyleft'', which means that derivative
-works of the document must themselves be free in the same sense. It
-complements the GNU General Public License, which is a copyleft
-license designed for free software.
-
-We have designed this License in order to use it for manuals for free
-software, because free software needs free documentation: a free
-program should come with manuals providing the same freedoms that the
-software does. But this License is not limited to software manuals;
-it can be used for any textual work, regardless of subject matter or
-whether it is published as a printed book. We recommend this License
-principally for works whose purpose is instruction or reference.
-
-@item
-APPLICABILITY AND DEFINITIONS
-
-This License applies to any manual or other work, in any medium, that
-contains a notice placed by the copyright holder saying it can be
-distributed under the terms of this License. Such a notice grants a
-world-wide, royalty-free license, unlimited in duration, to use that
-work under the conditions stated herein. The ``Document'', below,
-refers to any such manual or work. Any member of the public is a
-licensee, and is addressed as ``you''. You accept the license if you
-copy, modify or distribute the work in a way requiring permission
-under copyright law.
-
-A ``Modified Version'' of the Document means any work containing the
-Document or a portion of it, either copied verbatim, or with
-modifications and/or translated into another language.
-
-A ``Secondary Section'' is a named appendix or a front-matter section
-of the Document that deals exclusively with the relationship of the
-publishers or authors of the Document to the Document's overall
-subject (or to related matters) and contains nothing that could fall
-directly within that overall subject. (Thus, if the Document is in
-part a textbook of mathematics, a Secondary Section may not explain
-any mathematics.) The relationship could be a matter of historical
-connection with the subject or with related matters, or of legal,
-commercial, philosophical, ethical or political position regarding
-them.
-
-The ``Invariant Sections'' are certain Secondary Sections whose titles
-are designated, as being those of Invariant Sections, in the notice
-that says that the Document is released under this License. If a
-section does not fit the above definition of Secondary then it is not
-allowed to be designated as Invariant. The Document may contain zero
-Invariant Sections. If the Document does not identify any Invariant
-Sections then there are none.
-
-The ``Cover Texts'' are certain short passages of text that are listed,
-as Front-Cover Texts or Back-Cover Texts, in the notice that says that
-the Document is released under this License. A Front-Cover Text may
-be at most 5 words, and a Back-Cover Text may be at most 25 words.
-
-A ``Transparent'' copy of the Document means a machine-readable copy,
-represented in a format whose specification is available to the
-general public, that is suitable for revising the document
-straightforwardly with generic text editors or (for images composed of
-pixels) generic paint programs or (for drawings) some widely available
-drawing editor, and that is suitable for input to text formatters or
-for automatic translation to a variety of formats suitable for input
-to text formatters. A copy made in an otherwise Transparent file
-format whose markup, or absence of markup, has been arranged to thwart
-or discourage subsequent modification by readers is not Transparent.
-An image format is not Transparent if used for any substantial amount
-of text. A copy that is not ``Transparent'' is called ``Opaque''.
-
-Examples of suitable formats for Transparent copies include plain
-@sc{ascii} without markup, Texinfo input format, La@TeX{} input
-format, @acronym{SGML} or @acronym{XML} using a publicly available
-@acronym{DTD}, and standard-conforming simple @acronym{HTML},
-PostScript or @acronym{PDF} designed for human modification. Examples
-of transparent image formats include @acronym{PNG}, @acronym{XCF} and
-@acronym{JPG}. Opaque formats include proprietary formats that can be
-read and edited only by proprietary word processors, @acronym{SGML} or
-@acronym{XML} for which the @acronym{DTD} and/or processing tools are
-not generally available, and the machine-generated @acronym{HTML},
-PostScript or @acronym{PDF} produced by some word processors for
-output purposes only.
-
-The ``Title Page'' means, for a printed book, the title page itself,
-plus such following pages as are needed to hold, legibly, the material
-this License requires to appear in the title page. For works in
-formats which do not have any title page as such, ``Title Page'' means
-the text near the most prominent appearance of the work's title,
-preceding the beginning of the body of the text.
-
-A section ``Entitled XYZ'' means a named subunit of the Document whose
-title either is precisely XYZ or contains XYZ in parentheses following
-text that translates XYZ in another language. (Here XYZ stands for a
-specific section name mentioned below, such as ``Acknowledgements'',
-``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title''
-of such a section when you modify the Document means that it remains a
-section ``Entitled XYZ'' according to this definition.
-
-The Document may include Warranty Disclaimers next to the notice which
-states that this License applies to the Document. These Warranty
-Disclaimers are considered to be included by reference in this
-License, but only as regards disclaiming warranties: any other
-implication that these Warranty Disclaimers may have is void and has
-no effect on the meaning of this License.
-
-@item
-VERBATIM COPYING
-
-You may copy and distribute the Document in any medium, either
-commercially or noncommercially, provided that this License, the
-copyright notices, and the license notice saying this License applies
-to the Document are reproduced in all copies, and that you add no other
-conditions whatsoever to those of this License. You may not use
-technical measures to obstruct or control the reading or further
-copying of the copies you make or distribute. However, you may accept
-compensation in exchange for copies. If you distribute a large enough
-number of copies you must also follow the conditions in section 3.
-
-You may also lend copies, under the same conditions stated above, and
-you may publicly display copies.
-
-@item
-COPYING IN QUANTITY
-
-If you publish printed copies (or copies in media that commonly have
-printed covers) of the Document, numbering more than 100, and the
-Document's license notice requires Cover Texts, you must enclose the
-copies in covers that carry, clearly and legibly, all these Cover
-Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
-the back cover. Both covers must also clearly and legibly identify
-you as the publisher of these copies. The front cover must present
-the full title with all words of the title equally prominent and
-visible. You may add other material on the covers in addition.
-Copying with changes limited to the covers, as long as they preserve
-the title of the Document and satisfy these conditions, can be treated
-as verbatim copying in other respects.
-
-If the required texts for either cover are too voluminous to fit
-legibly, you should put the first ones listed (as many as fit
-reasonably) on the actual cover, and continue the rest onto adjacent
-pages.
-
-If you publish or distribute Opaque copies of the Document numbering
-more than 100, you must either include a machine-readable Transparent
-copy along with each Opaque copy, or state in or with each Opaque copy
-a computer-network location from which the general network-using
-public has access to download using public-standard network protocols
-a complete Transparent copy of the Document, free of added material.
-If you use the latter option, you must take reasonably prudent steps,
-when you begin distribution of Opaque copies in quantity, to ensure
-that this Transparent copy will remain thus accessible at the stated
-location until at least one year after the last time you distribute an
-Opaque copy (directly or through your agents or retailers) of that
-edition to the public.
-
-It is requested, but not required, that you contact the authors of the
-Document well before redistributing any large number of copies, to give
-them a chance to provide you with an updated version of the Document.
-
-@item
-MODIFICATIONS
-
-You may copy and distribute a Modified Version of the Document under
-the conditions of sections 2 and 3 above, provided that you release
-the Modified Version under precisely this License, with the Modified
-Version filling the role of the Document, thus licensing distribution
-and modification of the Modified Version to whoever possesses a copy
-of it. In addition, you must do these things in the Modified Version:
-
-@enumerate A
-@item
-Use in the Title Page (and on the covers, if any) a title distinct
-from that of the Document, and from those of previous versions
-(which should, if there were any, be listed in the History section
-of the Document). You may use the same title as a previous version
-if the original publisher of that version gives permission.
-
-@item
-List on the Title Page, as authors, one or more persons or entities
-responsible for authorship of the modifications in the Modified
-Version, together with at least five of the principal authors of the
-Document (all of its principal authors, if it has fewer than five),
-unless they release you from this requirement.
-
-@item
-State on the Title page the name of the publisher of the
-Modified Version, as the publisher.
-
-@item
-Preserve all the copyright notices of the Document.
-
-@item
-Add an appropriate copyright notice for your modifications
-adjacent to the other copyright notices.
-
-@item
-Include, immediately after the copyright notices, a license notice
-giving the public permission to use the Modified Version under the
-terms of this License, in the form shown in the Addendum below.
-
-@item
-Preserve in that license notice the full lists of Invariant Sections
-and required Cover Texts given in the Document's license notice.
-
-@item
-Include an unaltered copy of this License.

-Preserve the section Entitled ``History'', Preserve its Title, and add
-to it an item stating at least the title, year, new authors, and
-publisher of the Modified Version as given on the Title Page. If
-there is no section Entitled ``History'' in the Document, create one
-stating the title, year, authors, and publisher of the Document as
-given on its Title Page, then add an item describing the Modified
-Version as stated in the previous sentence.
-
-@item
-Preserve the network location, if any, given in the Document for
-public access to a Transparent copy of the Document, and likewise
-the network locations given in the Document for previous versions
-it was based on. These may be placed in the ``History'' section.
-You may omit a network location for a work that was published at
-least four years before the Document itself, or if the original
-publisher of the version it refers to gives permission.
-
-@item
-For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
-the Title of the section, and preserve in the section all the
-substance and tone of each of the contributor acknowledgements and/or
-dedications given therein.
-
-@item
-Preserve all the Invariant Sections of the Document,
-unaltered in their text and in their titles. Section numbers
-or the equivalent are not considered part of the section titles.
-
-@item
-Delete any section Entitled ``Endorsements''. Such a section
-may not be included in the Modified Version.
-
-@item
-Do not retitle any existing section to be Entitled ``Endorsements'' or
-to conflict in title with any Invariant Section.
-
-@item
-Preserve any Warranty Disclaimers.
-@end enumerate
-
-If the Modified Version includes new front-matter sections or
-appendices that qualify as Secondary Sections and contain no material
-copied from the Document, you may at your option designate some or all
-of these sections as invariant. To do this, add their titles to the
-list of Invariant Sections in the Modified Version's license notice.
-These titles must be distinct from any other section titles.
-
-You may add a section Entitled ``Endorsements'', provided it contains
-nothing but endorsements of your Modified Version by various
-parties---for example, statements of peer review or that the text has
-been approved by an organization as the authoritative definition of a
-standard.
-
-You may add a passage of up to five words as a Front-Cover Text, and a
-passage of up to 25 words as a Back-Cover Text, to the end of the list
-of Cover Texts in the Modified Version. Only one passage of
-Front-Cover Text and one of Back-Cover Text may be added by (or
-through arrangements made by) any one entity. If the Document already
-includes a cover text for the same cover, previously added by you or
-by arrangement made by the same entity you are acting on behalf of,
-you may not add another; but you may replace the old one, on explicit
-permission from the previous publisher that added the old one.
-
-The author(s) and publisher(s) of the Document do not by this License
-give permission to use their names for publicity for or to assert or
-imply endorsement of any Modified Version.
-
-@item
-COMBINING DOCUMENTS
-
-You may combine the Document with other documents released under this
-License, under the terms defined in section 4 above for modified
-versions, provided that you include in the combination all of the
-Invariant Sections of all of the original documents, unmodified, and
-list them all as Invariant Sections of your combined work in its
-license notice, and that you preserve all their Warranty Disclaimers.
-
-The combined work need only contain one copy of this License, and
-multiple identical Invariant Sections may be replaced with a single
-copy. If there are multiple Invariant Sections with the same name but
-different contents, make the title of each such section unique by
-adding at the end of it, in parentheses, the name of the original
-author or publisher of that section if known, or else a unique number.
-Make the same adjustment to the section titles in the list of
-Invariant Sections in the license notice of the combined work.
-
-In the combination, you must combine any sections Entitled ``History''
-in the various original documents, forming one section Entitled
-``History''; likewise combine any sections Entitled ``Acknowledgements'',
-and any sections Entitled ``Dedications''. You must delete all
-sections Entitled ``Endorsements.''
-
-@item
-COLLECTIONS OF DOCUMENTS
-
-You may make a collection consisting of the Document and other documents
-released under this License, and replace the individual copies of this
-License in the various documents with a single copy that is included in
-the collection, provided that you follow the rules of this License for
-verbatim copying of each of the documents in all other respects.
-
-You may extract a single document from such a collection, and distribute
-it individually under this License, provided you insert a copy of this
-License into the extracted document, and follow this License in all
-other respects regarding verbatim copying of that document.
-
-@item
-AGGREGATION WITH INDEPENDENT WORKS
-
-A compilation of the Document or its derivatives with other separate
-and independent documents or works, in or on a volume of a storage or
-distribution medium, is called an ``aggregate'' if the copyright
-resulting from the compilation is not used to limit the legal rights
-of the compilation's users beyond what the individual works permit.
-When the Document is included in an aggregate, this License does not
-apply to the other works in the aggregate which are not themselves
-derivative works of the Document.
-
-If the Cover Text requirement of section 3 is applicable to these
-copies of the Document, then if the Document is less than one half of
-the entire aggregate, the Document's Cover Texts may be placed on
-covers that bracket the Document within the aggregate, or the
-electronic equivalent of covers if the Document is in electronic form.
-Otherwise they must appear on printed covers that bracket the whole
-aggregate.
-
-@item
-TRANSLATION
-
-Translation is considered a kind of modification, so you may
-distribute translations of the Document under the terms of section 4.
-Replacing Invariant Sections with translations requires special
-permission from their copyright holders, but you may include
-translations of some or all Invariant Sections in addition to the
-original versions of these Invariant Sections. You may include a
-translation of this License, and all the license notices in the
-Document, and any Warranty Disclaimers, provided that you also include
-the original English version of this License and the original versions
-of those notices and disclaimers. In case of a disagreement between
-the translation and the original version of this License or a notice
-or disclaimer, the original version will prevail.
-
-If a section in the Document is Entitled ``Acknowledgements'',
-``Dedications'', or ``History'', the requirement (section 4) to Preserve
-its Title (section 1) will typically require changing the actual
-title.
-
-@item
-TERMINATION
-
-You may not copy, modify, sublicense, or distribute the Document except
-as expressly provided for under this License. Any other attempt to
-copy, modify, sublicense or distribute the Document is void, and will
-automatically terminate your rights under this License. However,
-parties who have received copies, or rights, from you under this
-License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-@item
-FUTURE REVISIONS OF THIS LICENSE
-
-The Free Software Foundation may publish new, revised versions
-of the GNU Free Documentation License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns. See
-@uref{http://www.gnu.org/copyleft/}.
-
-Each version of the License is given a distinguishing version number.
-If the Document specifies that a particular numbered version of this
-License ``or any later version'' applies to it, you have the option of
-following the terms and conditions either of that specified version or
-of any later version that has been published (not as a draft) by the
-Free Software Foundation. If the Document does not specify a version
-number of this License, you may choose any version ever published (not
-as a draft) by the Free Software Foundation.

-
-@page
-@heading ADDENDUM: How to use this License for your documents
-
-To use this License in a document you have written, include a copy of
-the License in the document and put the following copyright and
-license notices just after the title page:
-
-@smallexample
-@group
- Copyright (C) @var{year} @var{your name}.
- Permission is granted to copy, distribute and/or modify this document
- under the terms of the GNU Free Documentation License, Version 1.2
- or any later version published by the Free Software Foundation;
- with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
- Texts. A copy of the license is included in the section entitled ``GNU
- Free Documentation License''.
-@end group
-@end smallexample
-
-If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
-replace the ``with@dots{}Texts.'' line with this:
-
-@smallexample
-@group
- with the Invariant Sections being @var{list their titles}, with
- the Front-Cover Texts being @var{list}, and with the Back-Cover Texts
- being @var{list}.
-@end group
-@end smallexample
-
-If you have Invariant Sections without Cover Texts, or some other
-combination of the three, merge those two alternatives to suit the
-situation.
-
-If your document contains nontrivial examples of program code, we
-recommend releasing these examples in parallel under your choice of
-free software license, such as the GNU General Public License,
-to permit their use in free software.
