Also, what were the reasons for printing them out?
Mainly to go through and understand other peoples' code. The beauty of open-source is that you can stand on the shoulders of others. But you have to know what they were doing so that you can see whether it would be suitable for your project, and what changes you would need to make to make that previous code work for you.
('Cut 'n' Paste' does not work. You need to suit the code to the project.)
