+Unshelving will take a shelved P4 changelist, and produce the equivalent git commit
+in the branch refs/remotes/p4-unshelved/<changelist>.

+The git commit is created relative to the current origin revision (HEAD by default).

+created based on that.

+The origin revision can be changed with the "--origin" option.

+Hook for submit
+~~~~~~~~~~~~~~~
+The `p4-pre-submit` hook is executed if it exists and is executable.
+The hook takes no parameters and nothing from standard input. Exiting with

+One usage scenario is to run unit tests in the hook.
