Because we will be binary-incompatible with the existing libcurl4 packages,
so we want to enforce a rebuild of all packages built against the current
version and to protect users from having incompatible versions installed

Just rolling back the package name completely is the simplest name change
option that I see; you could reintroduce libcurl3* /and/ rename the current
libcurl4 packages to something else, but I think that's unnecessary
complexity, especially given that we would ideally keep libcurl3* around
anyway through the release of lenny to make the upgrade process as smooth as

SSL stuff is part of the base system; libssl0.9.8 and libgnutls13 are both
Priority: important.  I don't think SSL-less systems are a relevant use

Yes, except for the part where it's harder to keep broken package
combinations from trickling into testing. :)
