NAME
       autoreconf - Update generated configuration files

SYNOPSIS
       autoreconf [OPTION]... [DIRECTORY]...

DESCRIPTION
       Run `autoconf' (and `autoheader', `aclocal', `automake',
       `autopoint' (formerly  `gettextize'),  and  `libtoolize'
       where  appropriate)  repeatedly  to remake the GNU Build
       System files in specified DIRECTORIES and  their  subdi-
       rectories (defaulting to `.').

       By  default,  it only remakes those files that are older
       than their sources.  If you install new versions of  the
       GNU  Build  System, you can make `autoreconf' remake 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

       --no-recursive
              don't rebuild sub-packages

       -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

              user redefinitions of Automake rules or variables

       `portability'
              portability  issues  (default  in  gnu  and gnits
              modes)

       `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, M4, and MAKE
