[★] Acheivement Unlocked: Serving static content with Flask.

[★] Acheivement Unlocked: Generating static content from HAML.
[★] Achievement Unlocked: Building HAML from a Makefile.

once upon a time.  Cake and Grunt and Gulp and all the rest are
task runners, not dependency managers, and will Rebuild The World
every time.
