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 direc-
    tory trees driven by CONFIGURE-AC (defaulting to `.').

    By default, it only remakes those files that are older than their pre-
    decessors.  If you install new versions of the GNU Build System, run-
    ning `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

    `obsolete'
    obsolete constructs

    `portability'

    `syntax'
    dubious syntactic constructs

    `all' all the warnings

    `no-CATEGORY'
    turn off the warnings on CATEGORY
