.TH AUTORECONF "1" "March 2017" "GNU Autoconf 2.69" "User Commands"
.SH NAME
autoreconf \- Update generated configuration files
.SH SYNOPSIS
.B autoreconf
[\fI\,OPTION\/\fR]... [\fI\,DIRECTORY\/\fR]...
.SH DESCRIPTION
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 `.').
.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.
