Thanks for the speedy reply, I had figured after playing around a bit with it.... For other "slow" users like me who don't get it immediately and may be reading this, it's a command to run from the command prompt. What I did was to copy the entire "Bones" project folder to the desktop, then changed the command directory to my Desktop and ran this command:
C:\.......\Bones\script\jmeOgre2Bones -out ninja.group.bones -in ninja.mesh.xml
Thanks for your help Raft.
