   3# An example hook script to verify what is about to be committed.
   4# Called by git-commit with no arguments.  The hook should
   5# exit with non-zero status after issuing an appropriate message if
   6# it wants to stop the commit.
   7#
   8# To enable this hook, make this file executable.

  10# This is slightly modified from Andrew Morton's Perfect Patch.
  11# Lines you introduce should not have trailing whitespace.
  12# Also check for an indentation that has SP before a TAB.
