updates to reflect current status in Debian land, and added some known

differences between OpenSSL and GnuTLS (that is probably a suitable subject
for a separate document...)

The only problem is thus for distributions that want to offer libcurl
versions built with more than one SSL/TLS library.
Debian is now (since mid September 2005) providing two different devel
packages, one for libcurl built with OpenSSL and one built with GnuTLS. They
use different .so names and can this both be installed in a single system
simultaneously. This has previously been said as a transitional system not
desired to keep in the long run.
Since multiple libcurl binaries using different names are ruled out, we need
to come up with a way to have one single libcurl that someone uses different
underlying libraries. The best(?) approach currently suggested involves this:
