I forgot to say, the aim is usually to integrate it into a bigger project that I'm writing by myself. The working code is usually for interfacing to libraries I didn't write - I could spend a year reading every line of code for a given library and understanding everything it does, and then realise it doesn't do what I want. The working code is to see what it can do first, or to kick it closer to what I want - only when I know it can do it will I spend the time to fully understand what's going on. Otherwise a hundred lifetimes wouldn't be enough to go through the amount freely available crapware out there.
