The Jackhammer Map Format (JMF) is a binary file format used by 
J.A.C.K. to store map project data before being exported to MAP, like RMF. Unlike RMF, JMF supports objects being part of multiple visgroups, KVs longer than 15 characters, and Quake III patch meshes. Additionally, it can store paths in a slightly different manner, optimized for Jack's Path Tool.
