Odin is a simpler, more reliable, and more powerful replacement for Make. It is designed to combine the simplicity and elegance of the original Make program with the power of the latest super-Makes. Some of Odin's features include: building several variants concurrently from a single source tree; parallel builds on multiple remote hosts; persistent dependency database with incremental update; building directly from arbitrary versions of RCS and SCCS files, without requiring checkout of working copy; complete separation between build rules and system definition
