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 (comma-separated list accepted)

   Warning categories are:
       cross  cross compilation issues

       gnu    GNU coding standards (default in gnu and gnits modes)

       obsolete
              obsolete features or constructions (default)

       override
              user redefinitions of Automake rules or variables

       portability
              portability issues (default in gnu and gnits modes)

       portability-recursive
              nested Make variables (default with -Wportability)

       extra-portability
              extra portability issues related to obscure tools

       syntax dubious syntactic constructs (default)

       unsupported
              unsupported or incomplete features (default)

   -W also understands:
       all    turn on all the warnings

       none   turn off all the warnings

       no-CATEGORY
              turn off warnings in CATEGORY

       error  treat all enabled warnings as errors

   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.
