Testing source snippets

Hi everyone,

At last year's PyCon at the author BoF there was some discussion of the 
difficulty of testing code snippets embedded in a book or article's 
text. In the course of revising the Quick Python Book for Python 3.x (a 
project now finished!) I came up with a little program to doctest my 
interactive shell snippets and optionally save them into a text file for 
distribution with the book.

I finally got around to cleaning up the code and putting it online, so 
if anyone is interested, it's called doctester and lives at 
http://bitbucket.org/vceder/doctester, and the wiki documentation there 
pretty much explains how it works.

It's really not much, just a way to copy and paste snippets and run 
doctest on them, but it did save me a fair amount of time and helped 
keep the code examples in my book (I hope) fairly clean.

In looking at it, I can think of about a hundred enhancements that could 
be made, but since this project is done, I probably won't work on it for 
a while. So if it's of use to anyone else, feel free to take it for what 
it's worth.

Cheers,
