.TH AUTORECONF "1" "January 2021" "GNU Autoconf 2.71" "User Commands"
.SH NAME
autoreconf \- Update generated configuration files
.SH SYNOPSIS
.B autoreconf
[\fI\,OPTION\/\fR]... [\fI\,DIRECTORY\/\fR]...
.SH 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 '.').
.PP
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.
