Indeed http://isabelle.in.tum.de/repos/isabelle is pull-only.  In 
principle we could open push-access (via the ssh protocol of Mercurial) 
any time.  But pushing back would eventually cause conflicts with the 
automatic conversion process that applies changes coming from the CVS, and 
somebody would have to merge manually all the time.

In other words, the present Mercurial setup is essentially read-only while 
the Isabelle CVS at Munich is still being changed.

I have seen some scripts glued together for that, but they do not look 
very convincing.  Since the point of the conversion is to simplify our 
life, it is better to give up legacy altogether.
