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.
