I know of SBCL, CLISP, and PLT also doing this, but much more sophisticated for the former 2. --=20 Our last-ditch plan is to change the forums into a podcast, then send RSS feeds into the blogosphere so our users can further debate the legality of mashups amongst this month's 20 'sexiest' gadgets. --Richard "Lowtax" Kyanka --=-EHCgOb/2wd7Z4fuUN3b7 Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) iD8DBQBHVRRyYWjD35Pp0wIRAspTAKChzYiWk4kI0zKqGxg8tGbEc9OkZQCdELcB 5OMDxvIZavg4muI4AYWH6ic= =h2NG -----END PGP SIGNATURE----- --=-EHCgOb/2wd7Z4fuUN3b7-- --===============1312182723== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Guile-user mailing list Guile-user@gnu.org http://lists.gnu.org/mailman/listinfo/guile-user --===============1312182723==--
