NAME

       autoreconf - Update generated configuration files

SYNOPSIS

       autoreconf [OPTION] ... [CONFIGURE-AC or DIRECTORY] ...

DESCRIPTION

       Run   `autoconf'   (and   `autoheader',   `aclocal',   `automake',  `autopoint'  (formerly
       `gettextize'), and `libtoolize' where appropriate) repeatedly  to  remake  the  GNU  Build
       System  files in the DIRECTORIES or the directory trees driven by CONFIGURE-AC (defaulting
       to `.').

       By default, it only remakes those files that are older than their  predecessors.   If  you
       install  new  versions  of  the  GNU Build System, running `autoreconf' remakes all of the
       files by giving it the `--force' option.

   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

       -i, --install
              copy missing auxiliary files

       -s, --symlink
              with -i, install symbolic links instead of copies

       -m, --make
              when applicable, re-run ./configure && make

       -W, --warnings=CATEGORY
              report the warnings falling in CATEGORY [syntax]

   Warning categories include:
       `cross'
              cross compilation issues

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

       `obsolete'
              obsolete features or constructions

       `override'
              user redefinitions of Automake rules or variables

       `portability'
              portability issues

       `syntax'
              dubious syntactic constructs (default)

       `unsupported'
              unsupported or incomplete features (default)

       `all'  all the warnings

       `no-CATEGORY'
              turn off warnings in CATEGORY

       `none' turn off all the warnings

       `error'
              treat warnings as errors

       The environment variable `WARNINGS' is honored.  Some subtools might support other warning
       types, using `all' is encouraged.

   Library directories:
       -B, --prepend-include=DIR
              prepend directory DIR to search path

       -I, --include=DIR
              append directory DIR to search path

       The  environment  variables AUTOCONF, AUTOHEADER, AUTOMAKE, ACLOCAL, AUTOPOINT, LIBTOOLIZE
       are honored.
