modch (a small Go utility)

a "side project" is kind of an overstatement for what this is, but at some point someone said I should learn Go, so one of the things I did while trying to learn Go was make a small utility that converts Unix file permissions between octals and symbols. 

I still can't say I fully understand Go even after that, but it was fun to read a bunch of docs and write up a post about it afterwards.
