pre-commit hook to force Symfony coding standards

# The built-in scripts are mostly shell and PERL scripts, but you
# can use any scripting language you like as long as it can be run
# as an executable.
#
# An example hook script to verify what is about to be committed.
# Called by "git commit" with no arguments.  The hook should
# exit with non-zero status after issuing an appropriate message if
# it wants to stop the commit.

# Get some fancy colors :)
