$help = "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
" . Autom4te::ChannelDefs::usage . "
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.
