Yes, most people who have used this code in recent years have had to make heavy modifications and fix several bugs to get it working properly. It's mostly really great stuff, but it was written rather hastily.
Wait - was this open sourced _in_ 2011, or last edited then and open sourced only recently? The former doesn't sound right, because I was working in a similar area around that time and would've thought I'd have seen this earlier if it had been publicised.
SourceForge was absolutely amazing in 2000. It certainly hasn't kept up with technology, and is a horrible ad-infested mess now, but it (and its failed competitors, like Xnot if I remember the name correctly) played a huge role in promoting and distributing open source and Free software back in the day.
