-Usage: $0 [OPTION]... [TEMPLATE-FILE]
-
-Generate a configuration script from a TEMPLATE-FILE if given, or
-'configure.ac' if present, or else 'configure.in'. Output is sent
-to the standard output if TEMPLATE-FILE is given, else into
-'configure'.
-
-Operation modes:
- -h, --help print this help, then exit
- -V, --version print version number, then exit
- -v, --verbose verbosely report processing
- -d, --debug don't remove temporary files
- -f, --force consider all files obsolete
- -o, --output=FILE save output in FILE (stdout is the default)
- -W, --warnings=CATEGORY report the warnings falling in CATEGORY
-
-Warning categories include:
- cross cross compilation issues
- gnu GNU coding standards (default in gnu and gnits modes)
- obsolete obsolete features or constructions (default)
- override user redefinitions of Automake rules or variables
- portability portability issues (default in gnu and gnits modes)
- portability-recursive nested Make variables (default with -Wportability)
- extra-portability extra portability issues related to obscure tools
- syntax dubious syntactic constructs (default)
- unsupported unsupported or incomplete features (default)
- all all the warnings
- no-CATEGORY turn off warnings in CATEGORY
- none turn off all the warnings
-
-The environment variables 'M4' and 'WARNINGS' are honored.
-
-Library directories:
- -B, --prepend-include=DIR prepend directory DIR to search path
- -I, --include=DIR append directory DIR to search path
-
-Tracing:
- -t, --trace=MACRO[:FORMAT] report the list of calls to MACRO
- -i, --initialization also trace Autoconf's initialization process
-
-In tracing mode, no configuration script is created. FORMAT defaults
-to '\$f:\$l:\$n:\$%'; see 'autom4te --help' for information about FORMAT.
