   3  # An example hook script to verify what is about to be pushed.  Called by "git
   4  # push" after it has checked the remote status, but before anything has been
   5  # pushed.  If this script exits with a non-zero status nothing will be pushed.
   6  #
   7  # This hook is called with the following parameters:
   8  #
   9  # $1 -- Name of the remote to which the push is being done
  10  # $2 -- URL to which the push is being done
  11  #
  12  # If pushing without using a named remote those arguments will be equal.
  13  #
  14  # Information about the commits which are being pushed is supplied as lines to
  15  # the standard input in the form:
  16  #
  17  #   <local ref> <local oid> <remote ref> <remote oid>
  18  #
  19  # This sample shows how to prevent push of commits where the log message starts
  20  # with "WIP" (work in progress).
