commit d536c3e203a5613f5e91c5a9556057bd2eb5331e
Author: Shaun Ruffell <sruffell at digium.com>
Date:   Wed Jun 5 17:31:02 2013 -0500

    build_tools/dkms-helper: Helper script for DKMS integration.
    
    DKMS (Dynamic Kernel Module Support) [1] provides a mechanism where kernel
    modules can be automatically updated when a new kernel is booted.  This is a
    simple helper script to automate the process of adding dahdi-linux to the local
    DKMS system.
