Here’s the source code:
Looking for an OS X developer. The file browser and clipboard functions are win32 API, so they are the only things that should be changed. You could use FLTK’s own browser and do your OS X magic with the clipboard.
Please inform us if you’re going to develop this program further. I have other things going on at the moment, so there won’t be a new release in a while.
Just open psymachine.dev with DEV-C++ and it should compile fine if you have FLTK 1.1.7 installed.
