   - Description: This repository contains testing tools for C++, and is used in OSRF projects. The memory_tools API lets you intercept calls to dynamic memory calls like ```malloc``` and ```free```, and provides some convenience functions for differentiating between expected and unexpected calls to dynamic memory functions.
