       autoreconf - Update generated configuration files


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


       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 compilation issues

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

              obsolete features or constructions

              user redefinitions of Automake rules or variables

              portability issues

              dubious syntactic constructs (default)

              unsupported or incomplete features (default)

       ‘all’  all the warnings

              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.

   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.
