CTF is a common kind of 'hacking competition'. The acronym does, indeed, stand for 'Capture The Flag', but instead of the physical game, you get people competing to hack ('pwn') a piece of software.
Basically this is just a little library of utilities that come handy when playing CTF: hexing, assembly, shell code, etc. Think of it as a bunch of pre-made snippets that you'd normally reuse when trying to hack something.
