26Usage: $0 [OPTION]... [TEMPLATE-FILE]
27
28Generate a configuration script from a TEMPLATE-FILE if given, or
29\`configure.ac' if present, or else \`configure.in'.  Output is sent
30to the standard output if TEMPLATE-FILE is given, else into
31\`configure'.
32
33Operation modes:
34  -h, --help                print this help, then exit
35  -V, --version             print version number, then exit
36  -v, --verbose             verbosely report processing
37  -d, --debug               don't remove temporary files
38  -f, --force               consider all files obsolete
39  -o, --output=FILE         save output in FILE (stdout is the default)
40  -W, --warnings=CATEGORY   report the warnings falling in CATEGORY [syntax]
41
42Warning categories include:
43  \`cross'         cross compilation issues
44  \`obsolete'      obsolete constructs
45  \`syntax'        dubious syntactic constructs
46  \`all'           all the warnings
47  \`no-CATEGORY'   turn off the warnings on CATEGORY
48  \`none'          turn off all the warnings
49  \`error'         warnings are error
50
51The environment variables \`M4' and \`WARNINGS' are honored.
52
53Library directories:
54  -B, --prepend-include=DIR  prepend directory DIR to search path
55  -I, --include=DIR          append directory DIR to search path
56
57Tracing:
58  -t, --trace=MACRO[:FORMAT]  report the list of calls to MACRO
59  -i, --initialization        also trace Autoconf's initialization process
60
61In tracing mode, no configuration script is created.  FORMAT defaults
62to \`\$f:\$l:\$n:\$%'; see \`autom4te --help' for information about FORMAT.
