# File: FreeRTOS.py
# Author: Carl Allendorph
# Date: 05NOV2014
#
# Description:
# This file contains some python code that utilizes the GDB API
# to inspect information about the FreeRTOS internal state. The
# idea is to provide the user with the ability to inspect information
# about the tasks, queues, mutexs, etc.
