Helipad is a really simple "micro-framework" that makes it easy to do the stupid stuff really quickly on Google AppEngine.
As great as AppEngine is, it seemed like some stupid stuff (like the Hello World)
built with webapp was more verbose than it needed to be. I figured that there
must be a way to be a bit more terse without losing any clarity. This little file
has a few helpers that are just shorthand for things that you can do with webapp.
Getting started with helipad is simple. Put helipad.py file in the directory where
your application is and import helipad.
