Isn't this one of the reasons the client/server protocol was
designed for?  It's versioned, negotiates capabilities (on both
sides IIUC) and is well documented.  Plus there are plenty of
tools for network access from within your scripts.  And hasn't
there been some effort to build libs?  Doesn't use cvs such a lib

To cut it short:  I wouldn't go the route of parsing command
output.  Exactly for the reasons you state above.  I'd rather
look for a protocol that's made for machines instead of users. :)
