Description
I don't have a very fast internet connection (over the ocean) and one of the major problems is that I do not want to checkout packages that are already on my system. This is already handled by the -n (--no-cvs) option but I would really like the system to try checkout from cvs if the module is not in the current build tree.
Currently jhbuild simply just fails.
