Hey everybody, hope this isn't frowned upon/against the rules.
When reading through the HMH source files, I frequently wished for the ability to do a git (or svn) blame, to find out the commit (e.g. the day) a piece of code was introduced, so that I could go and watch the explanation for it. The current system doesn't really lend itself to that, however it's fairly easy to convert to a system that does.
So I wrote a shell (bash) script to make a git repository out of the code download. You need to be on a unix platform or windows with msysgit/gitbash installed. Drop the script into the unzipped handmade hero code download folder, and run it. Since it works for me, I figured I'd share it.
Anyway, the script is available here: http://pastebin.com/tf6X5jU2. Please don't use this to upload the HMH code to github or similar, but that should go without saying.
