SYNOPSIS

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

DESCRIPTION

       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 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

   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.
