That's beautiful. It may be a monster, but it started so small in 1992 - then was grown with loving care in 1993, 1994, 1995, 1998, 1999, 2001, 2002, 2004, 2005, 2008, and 2011!
I thinks that's just when the source control kicks in.
DannyBee claims that reload was started in the late 80s.
There are commits going back to 1988, but it looks like a lot of the early commits are out of order; the repository was (at least) converted from RCS to CVS to SVN to Git.
