I have a "src" folder for my own source code, or code I've contributed to, but do you have a separate folder for source code from other people? I.e. code you've downloaded just because there are no available binary packages? If so, what do you call it?

@dbdemon "xtern". Fine for me, but wouldn't use it in a shared context and expect anyone else to immediately get it.
