These are installation instructions for Bash.
+The simplest way to compile Bash is:
+
+ 1. `cd' to the directory containing the source code and type
+ `./configure' to configure Bash for your system. If you're using
+ `csh' on an old version of System V, you might need to type `sh
+ ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes some time. While running, it prints
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile Bash and build the `bashbug' bug reporting
+ script.
+
+ 3. Optionally, type `make tests' to run the Bash test suite.
+
+ 4. Type `make install' to install `bash' and `bashbug'. This will
+ also install the manual pages and Info file.
+
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package
-(the top directory, the `builtins' and `doc' directories, and the each
-directory under `lib'). It also creates a `config.h' file containing
-system-dependent definitions. Finally, it creates a shell script named
-`config.status' that you can run in the future to recreate the current
-configuration, a file `config.cache' that saves the results of its
-tests to speed up reconfiguring, and a file `config.log' containing
-compiler output (useful mainly for debugging `configure'). If at some
-point `config.cache' contains results you don't want to keep, you may
-remove or edit it.

If you need to do unusual things to compile Bash, please try to figure
out how `configure' could check whether or not to do them, and mail
script `support/mkconffiles' has been provided to automate the creation
of these files.

Optional Features
=================
The Bash `configure' has a number of `--enable-FEATURE' options, where
FEATURE indicates an optional part of Bash. There are also several
-`--with-PACKAGE' options, where PACKAGE is something like `gnu-malloc'
+`--with-PACKAGE' options, where PACKAGE is something like `bash-malloc'
or `purify'. To turn off the default use of a package, use
`--without-PACKAGE'. To configure Bash without a feature that is
enabled by default, use `--disable-FEATURE'.
`--with-afs'
Define if you are using the Andrew File System from Transarc.
+`--with-bash-malloc'
+ Use the Bash version of `malloc' in `lib/malloc/malloc.c'. This
+ is not the same `malloc' that appears in GNU libc, but an older
+ version derived from the 4.2 BSD `malloc'. This `malloc' is very
+ fast, but wastes some space on each allocation. This option is
+ enabled by default. The `NOTES' file contains a list of systems
+ for which this should be turned off, and `configure' disables this
+ option automatically for a number of systems.
+
`--with-curses'
Use the curses library instead of the termcap library. This should
be supplied if your system has an inadequate or incomplete termcap
2, but a modified version of the `malloc' from glibc version 1.
This is somewhat slower than the default `malloc', but wastes less
space on a per-allocation basis, and will return memory to the
