Chris@14: # An example hook script to verify what is about to be pushed.  Called by "git
Chris@14: # push" after it has checked the remote status, but before anything has been
Chris@14: # pushed.  If this script exits with a non-zero status nothing will be pushed.
Chris@14: #
Chris@14: # This hook is called with the following parameters:
Chris@14: #
Chris@14: # $1 -- Name of the remote to which the push is being done
Chris@14: # $2 -- URL to which the push is being done
Chris@14: #
Chris@14: # If pushing without using a named remote those arguments will be equal.
Chris@14: #
Chris@14: # Information about the commits which are being pushed is supplied as lines to
Chris@14: # the standard input in the form:
Chris@14: #
Chris@14: #   <local ref> <local sha1> <remote ref> <remote sha1>
Chris@14: #
Chris@14: # This sample shows how to prevent push of commits where the log message starts
Chris@14: # with "WIP" (work in progress).
