Yeah, they could use some work indeed. But for a Linux-only environment (which
LSB kind of implies) the test suite is pretty stable and good-working. But I
would certainly not turn down any offers that would improve it!

I don't quite agree that it would be "fairly limited" as it is still a very
useful and powerful library for HTTP and FTP. Still, having it added to LSB
without SSL would still be rather pointless since the majority of all users
would like to replace that with an SSL-capable one...

Ok, so there's no SSL libs and libcurl is "fairly limited" without SSL.
Doesn't this basically imply that there must be an SSL lib provided first?

I don't understand the difference nor what you ask of us. We provide a lib
that requires a supported SSL lib (one out of three possible for the moment)
for SSL/TLS. If you want that provided in some funny way, what do we need to
do to enable that? Or perhaps, what could we do wrong now that would precent
that?

Well, we are not responsible for what distros do or how they decide to ship
curl and libcurl. We are simply the makers of the tool and lib, we do not
create any packages used in Linux distros.

So, they may be very good or very bad, I actually wouldn't know.

Just more testing and time. I intend to announce it as "stable" in the 7.16.0
release, which is the next public release we'll make.
