 * Interface to Lisp string streams: make_string_input_stream,
   make_string_output_stream, get_output_stream_string


   New items in share:

 * vector3d package (thanks to Walter Eastes)

 * Script share/share_testsuite.mac to run tests in share

 * share/contrib/topoly.lisp: new functions elim and elim_allbut


   New items in tests:
