 # ftjam
 
+Jam is a small open-source build tool that can be used as a replacement for Make. Even though Jam is a lot simpler to use than Make, it is far more powerful and easy to master. It already works on a large variety of platforms (Unix, Windows, OS/2, VMS, MacOS, BeOS, etc.), it is trivial to port, and its design is sufficiently clear to allow any average programmer to extend it with advanced features at will.
+This is an improved version, named ‘FT Jam’, containing several enhancements (like the ability to run on Windows 9x systems, or additional compiler/toolset support).
