# $HELP
# -----
$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
                            (comma-separated list accepted)

" . 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.

The full documentation for Autoconf can be read via 'info autoconf',
