You are right. There isn’t one. But to aid you I have re-factored some of the code and have the source code for the Mesh Generator available to be downloaded at :
www.srinavinnair.com/downloads (MeshGen_Linux)
Unfortunately, I don’t have an executable ready to use, so you will have to build it in your version of Linux using this source code.
The executable should work the same way as the documentation states.
Do let me know if this works fine.
