/* This script is a local pre-commit hook script.
 * It's used to check whether the copyright year of modified files has been
 * bumped up to the current (2014) year.
 *
 * Only *.cpp, *.h and *.idl files are checked
 *
 * Set the local hook scripts like this (pre-commit hook):
 * WScript path/to/this/script/file.js
 * and set "Wait for the script to finish"
