usage="\
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 [syntax]
Warning categories include:
\`cross' cross compilation issues
\`obsolete' obsolete constructs
\`syntax' dubious syntactic constructs
\`all' all the warnings
\`no-CATEGORY' turn off the warnings on CATEGORY
\`none' turn off all the warnings
\`error' warnings are error
The environment variable \`WARNINGS' is 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 report the list of calls to MACRO
-i, --initialization also trace Autoconf's initialization process
In tracing mode, no configuration script is created.
Report bugs to <bug-autoconf@gnu.org>."
