NAME


autoreconf - Update generated configuration files

SYNOPSIS


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

DESCRIPTION


Run 'autoconf' and, when needed, 'aclocal', 'autoheader', 'automake',
'autopoint' (formerly 'gettextize'), 'libtoolize', 'intltoolize', and
'gtkdocize' to regenerate 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' 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 generated and standard files obsolete

-i, --install
copy missing standard auxiliary files

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

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

-m, --make
