If you are a programmer, clone the code from github.
You are right about a demo, but this is a small project that I really wrote for myself, and shared it (and the code) as an after thought. This is really a 'scratch my own itch' project, like my cookingspace.com site that I use to track my vitamin K input - I could not find any other recipe sites that would do that for me when I wrote cookingspace.
Anyway, thanks for the idea: I'll add a PDF download link tomorrow with screenshots and a page or two of text describing why I did not like any of the other 'getting stuff done' sites.
