     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).
