A look inside the developer's toolbelt (git.savannah.gnu.org)

For a good time,take a look at some of the commits on c99-to-c89.diff. Looking at a diff-diff makes my eyes cross a little.

I'm always looking for sources like these, but I can never find a place that let's me just look at file 1 and move on from there.

If anyone's got any resources that might give me an idea of the file progression – from OS to OS with teeth – I'd be extremely obliged. I'd like to grok *nix.

I'd really rather not look inside anyone's toolbelt. Their toolpants just might slip down. That would be embarassing for all concerned.
