Subject: Gross hack to add https support to guile-www
Date: 15 Aug 2001 10:52:54 -0700
To: twp@tezcat.com, guile-sources@gnu.org


This code works for me, but is pretty ugly because

* it assumes you've got SSL-enabled lynx on your PATH, and

* it exports a function that really should be local to its module.

These patches are against recent CVS sources of guile/guile-www.  That
directory doesn't seem to have been touched since February.
