Name: Basic Tumbler.com API Utility
Version: 1.0
Author: Josh Nichols <mrblank@gmail.com>

Data source:
Requires a Dynamic XML data source using Tumblr.com's API named "get-tumblr". API documentation: http://www.tumblr.com/api
Example: http://mrblank.tumblr.com/api/read/
To do:
Include some starter CSS rules.
