Our intent is to make it easy to use all "library" pieces of the code, in
both free and proprietary software.  Hence most code that we expect to be
linked into a client application is covered by an MIT-style license:

A few files in the ao_sysdeps directory were inherited in part from the
Boehm-Demers-Weiser conservative garbage collector, and are covered by
its license, which is similar in spirit:

A few files are covered by the GNU General Public License.  (See file
"COPYING").  Currently this applies only to test code and sample
applications.  This should have no effect on linking "library"
routines into proprietary applications.

In the future, legal considerations may make it desirable to also cover
some newly added library routines under the GPL.  If so, these will be
clearly separated, and not implicitly linked into existing libraries.
