This is the FRoSt Lab at BYU's fork of LCM. It contains only minor modifications to make it compatible with python3, as well as publish it as a pypi package (to make installable from pip).
LCM is a set of libraries and tools for message passing and data marshalling,
targeted at real-time systems where high-bandwidth and low latency are
critical. It provides a publish/subscribe message passing model and automatic
marshalling/unmarshalling code generation with bindings for applications in a
variety of programming languages.
