# Usage: add this file to your project's .git/hooks directory. Rename it to
# just 'pre-commit' and make it executable.
# Now, when you change some files in repository and try to commit these
# changes, git will run this script right before commit.
#
# This script checks:
# C/C++ files with cppcheck
# XML files with xmllint
