       autoconf - Generate configuration scripts


       autoconf [OPTION]... [TEMPLATE-FILE]


       Generate  a  configuration  script  from  a  TEMPLATE-FILE if given, or
       `' if present, or else `'.  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 compilation issues

              obsolete constructs

              dubious syntactic constructs

       `all'  all the warnings

              turn off the warnings on CATEGORY

       `none' turn off all the warnings

              warnings are error

       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

       -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.
