reST is one of my favorite tools right now. It’s easy to read / write, produce some nice HTML output (as in http://respyre.org for example ).
The only issue for me is that i’ve been unable to write some custom tag, but this morning i just discover this: Making docutils do python syntax highlighting</a> on Bob Rant blog. So guess what .. i gonna implement this for my new blog system :)
Many thanks Bob
