NAME

6       autoreconf - Update generated configuration files
7

SYNOPSIS

9       autoreconf [OPTION]... [DIRECTORY]...
10

DESCRIPTION

12       Run  'autoconf'  and, when needed, 'aclocal', 'autoheader', 'automake',
13       'autopoint' (formerly 'gettextize'), 'libtoolize',  'intltoolize',  and
14       'gtkdocize'  to  regenerate the GNU Build System files in specified DI‐
15       RECTORIES and their subdirectories (defaulting to '.').
16
17       By default, it only remakes those  files  that  are  older  than  their
18       sources.   If you install new versions of the GNU Build System, you can
19       make 'autoreconf' remake all of the files by giving  it  the  '--force'
20       option.
