-# Pre-commit hook for running checkstyle on changed Java sources
-#
-# To use this you need:
-# 1. checkstyle's jar file somewhere
-# 2. a checkstyle XML check file somewhere
-# 3. To configure git:
-#   * git config --add checkstyle.jar <location of jar>
-#   * git config --add checkstyle.checkfile <location of checkfile>
-#   * git config --add java.command <path to java executale> [optional
-#     defaults to assuming it's in your path]
-# 4. Put this in your .git/hooks directory as pre-commit
-#
-# Now, when you commit, you will be disallowed from doing so
-# until you pass your checkstyle checks.
