Good point.

That limits non-GPL licensed packages to an aclocal.m4 based 
distribution method, rather than shipping the files and m4_including 
them with automake-1.8 and higher :-(

Also, I'm not sure whether `input to GNU Automake' is good legalese for
`feed it to aclocal'?

Here's another:

As a special exception to the GNU General Public License, if you 
distribute this file as part of a package that uses the file as input
to programs that are shipped as part of GNU Autoconf, GNU Automake, or 
GNU Libtool, then you may distribute this file for that purpose under
the same terms that you use for the rest of the package.

Cheers,
        Gary.
