The only thing I'd add is maybe porting over the "directory already exists"
from one of the other scripts (e.g. either delete and repull, or go into the
directory and pull).
Right now clone gives an error that the dir already exists, which I believe
means it won't pull or update, so I'm not sure if things get handled
appropriately lining up source to jira.
Having said that, this is really helpful to have fixed, thanks!
