-The development process of trace-cruncher is strongly coupled to the development of the Linux kernel tracing libraries [libtraceevent](https://git.kernel.org/pub/scm/libs/libtrace/libtraceevent.git), [libtracefs](https://git.kernel.org/pub/scm/libs/libtrace/libtracefs.git/) and [KernelShark](https://git.kernel.org/pub/scm/utils/trace-cmd/kernel-shark.git/). Because of this reason we adopt and follow the development workflow established by those projects.
