MegaTunix is the only native tuning software that supports the majority of 
megasquirt firmwares. It has been redesigned in such a way as to be extensible
to support new firmware variants with little to no new code needing to be 
written. The new design permits the gui tabs that relate to MegaSquirt 
variables to be redesigned using the Glade GUI designer for windows or Glade 
gui designer for Unix to change or alter the gui look/feel to accomodate new 
controls on more advanced firmwares.

This requires gtkglext.
