+/**
+ * Git COMMIT-MSG hook for validating commit message
+ * See https://docs.google.com/document/d/1rk04jEuGfk9kYzfqCuOlPTSJw3hEDZJTBN5E5f1SALo/edit
+ *
+ * This CLI supports 3 usage ways:
+ * 1. Default usage is not passing any argument. It will automatically read from COMMIT_EDITMSG file.
+ * 2. Passing a file name argument from git directory. For instance GIT GUI stores commit msg @GITGUI_EDITMSG file.
+ * 3. Passing commit message as argument. Useful for testing quickly a commit message from CLI.
+ *
+ * Installation:
+ * >> cd <angular-repo>
+ * >> ln -s ../../validate-commit-msg.js .git/hooks/commit-msg
