     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).
