I used this to create an application for a client, the Professional Aviation Specialists of Illinois, Chapter 3. The app gives them a searchable, indexed reference for documentation on the union constitution and contract with the Federal Aviation Administration. It also feeds live updates from the their blog.
As my first real forray into mobile development, I enjoyed and learned alot from the project. I used plenty of Python scripting, which I grew to love, to parse the raw text from documents and format it into markup. This required the liberal use of Regular Expressions.
