+# TODO: someday include the zsdcc stuff. Probably sometime after z88dk's
+# 2.0 release. If no 2.0 release exists by, say, the start of 2019, I'll
+# probably change this build so it works with a git snapshot instead
+# of a release. I'll admit, my motivation for that will be that I want
+# to have a C compiler that targets Pac-Man arcade hardware (the 1.99B
+# release doesn't, current git does).
