Program for editing PDF files

[bplus]

Well key to building an editor is looking up it's header file format. It does help having used PDF often so you know what it is supposed to do and that you coded it to do that. Plus you might not need it to do half the things its capable of doing... plus have some practice with binary access. Here is where LB/JB shine with their GUI, that has an Editor control and can do multi-screens.
