Apple's currency-conversion example is simple enough that essentially the only things one learns in implementing it are Cocoa APIs. It can therefore serve as a way to illustrate how OpenMCL's Cocoa bridge supports those APIs, and so is a good candidate for a first example program.

It looks like we could save a byte of space by using a shorter encoding of MOV in the following cases.

Images built with this change applied seem to work fine. The images are abut 28K smaller---a savings of about 0.2%, if it's even meaningful to make such comparisons.

The ApplicationServices framework includes important image processing classes needed for mapping files to OpenGL textures. Likewise, QuartzCore and Foundation have useful routines for other graphical applications.

I'm attaching the populate.sh files I used to generate the CDB files for my use.
