.SH DESCRIPTION
Run `autoconf' and `autoheader' where appropriate) repeatedly to
remake the Autoconf `configure' scripts and configuration header
templates in the directory tree rooted at the current directory.

predecessors.  If you install a new version of Autoconf, running
`autoreconf' remakes all of the files by giving it the `\-\-force'
option.
