I installed Quantz for Mac OS X this weekend and the executable is just 24kB. I could not find a Gambit framework in the application bundle, nor in /Library. I wonder how they did that...
Well, I do not know the background of the programmers, but as I have been very close to the "demoscene", there are some tricks I know: - use a home made linker - use a (de)compressor - fork the compiler to keep only what you need (which *can* be an option if you have time for that, and will get money back too) - hide the framework in the README.TXT (yeah, that's cheating…) - check if the framework is not already on the system prior to deciding whether you install it or not…
By the way, if you're on a mac, you should be able to ltrace, ktrace and strace the program. If the framework is somewhere else, you'll find it quickly I guess. Just be sure that {l,s,k}tracing the binary is legal (I don't know if that's considered debugging and/or reverse engineering).
P!
