Would it be possible to allow the HowTos to be written in Markdown (or Textile). Both are some kind of preprocessors, allowing you to write texts in a nice syntax.
There are also a lot of GUI applications like Mou for OSX that allow you to export to HTML or PDF -> so using common HTML elements would be enough as well
E.g. <pre><code> for codeblocks instead of the <p class="command"> etc.
It would make writting tutorials much easier
