       autoreconf - Update generated configuration files

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

       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
       subdirectories (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'

   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

              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 compilation issues

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

              obsolete features or constructions

              dubious syntactic constructs (default)

              unsupported or incomplete features (default)

              turn off warnings in CATEGORY

       `none' turn off all the warnings

              treat warnings as errors

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

              prepend directory DIR to search path

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

       ACLOCAL, AUTOPOINT, LIBTOOLIZE, M4, and MAKE are honored.
