[X2Go-User] testing session broker in WSGI/plain/inifile configuration

[Short, Kermit]

Thanks Mike!  That brings up a few questions for me, though.  I'm at home, and don't have to contend with the firewalls on the workplace networks, but I can never seem to clone any of the source repos.  More than likely, I'm doing something wrong with the git command, but whenever I try to clone through our (mandatory) http proxy, the clone command just sits there for about 5 minutes, and then errors out.

I just tried to clone the x2gobroker.git project (at home) as follows:
git clone http://git.x2go.org/projects x2gobroker.git
or subsequently:
git clone http://git.x2go.org x2gobroker.git

and I get the following error (from either repository path):
Initialized empty Git repository in /lclhome/k_short/work/x2gobroker.git/.git/
warning: remote HEAD refers to nonexistent ref, unable to checkout.

If you can help me remove the idiot factor with my clone attempts, I'd appreciate it!

Once I do manage to get a clone of the source, should I be uninstalling the existing x2gobroker-* packages installed on my session broker server?  How would I then go about installing the binaries after configure/make/make install from source?  Can I leave at least something that I've done or do I blow it all away and start over with nightly build codes?

I really have to release 0.0.3.0 which is currently in x2gobroker.git master branch and in our nightly builds.

Please use that version (which still is a development snapshot and a preview, but in terms of the agent more robust).
