I'd like to be able to search the Julia code in the registered packages, just to see if
changes that I'm thinking of making (like `isvalid(string, index)` -> `haskey(string, index)`, which somebody else proposed)
would be likely to cause breakage.
Would the best way of doing this be to try to clone all of the packages? Any idea how much space that would take? I can use the shallow-clone feature that somebody brought up recently.
If so, is there an easy way to do that?
Thanks, Scott
