Crunchy is an application that formats and delivers html-written Python tutorials inside a browser window, adding interactive elements and snazzy navigation.

To get started with Crunchy, download the code and set up an account by typing python account_manager.py (see readme.html for more precise instructions). Then, go through the tutorial (launch Crunchy by typing python crunchy.py and you should be all set).

There are now a few screencasts of an older version of Crunchy. They been recorded as "live" sessions and, as such, are not very polished but do give an overview of Crunchy's capabilities.

It is possible to launch processes from Crunchy using a different Python version than the default. For example, suppose you have Python 2.5 and Python 3.0a2 installed on your system. You can start Crunchy using Python 2.5 (it is not compatible with 3.0 - yet) and, from within Crunchy/Firefox, execute some code (as an external process) using Python 3.0a2. Some examples are provided in the Tests section.
