-Patch for the MC/DC checker
----------------------------
-
-Currently the MC/DC checker works for simple C programs but crashes when run against code in several ROS packages. A `patch <https://gist.githubusercontent.com/iche033/ef0d23c85f4d810fa26c722027894c91/raw/f0a9f48abffff0101b9e7f2a2fd94f79cafe360e/mcdc_checker.patch>`_ with minor code changes to checker code is needed to avoid the crash. See instructions below for applying the patch to the checker.

 How to run the MC/DC checker

-   docker cp mcdc_checker.py `docker ps | grep mcdc-checker | awk '{print $1;}'`:/app/src/mcdc_checker.py

 The ``-a`` flag tells the check to run recursively on all files in this directory. You should see the script start processing the source code and generating output. See notes below for more info about possible error messages.
