[PATCH] Support for multiple licenses.

[Sergey Poznyakoff]

Hello,

When copying required files, automake in its current form supposes
that the package being 'automade' falls under the terms of only
one license (either GPL or Lesser GPL). However, some packages
are distributed under the terms of the two licenses. For example,
GNU Mailutils package distributes its libraries under LGPL, and
binary programs under GPL. Thus, in Mailutils we need both COPYING
and COPYING.LIB to be distributed. 

I propose to add a new switch 'multiple-licenses' which would tell
automake that the package needs both files. Then, if one sets in the
Makefile.am

AUTOMAKE-OPTIONS = gnu multiple-licenses

and copies COPYING.LIB to the root directory of his package, then
automake will add both COPYING and COPYING.LIB to the DIST_COMMON
variable of the resulting Makefile.in.

Attached is the patch that implements this idea.

Regards,
Sergey
