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 `.'). By default, it only remakes those files that are older than their sources.
