JIT makes it easy to work on projects involving multiple different repositories. It works
with the assumption that the project is organized with a root directory containing all
repositories for the project. The following are the available commands (prepended with jit):
all Display all current branches.
co <branch name> Checks out this branch on all repos where it exists.
dirty Display all repos with uncommitted changes.
master Checkout master branch on all repos.
mine Display all branches for all repos.
pull Pull from remote origin on all repos.
show <branch name> Shows all repos where this branch exists.
