BullDoc is generally for the projects developed on PHP and which uses SVN or other source control system. The project was built with the following objectives in mind: 1. The documentation sources should be stored in the same repository as the code. 2. The sources should be text files, so SVN could track changes and we always could extract documentation version appropriate to the code 3. There should be convenient to view the result of our authoring. Just open page in browser and see. No additional compiling. It should be easy to edit text – just press “edit” button and make correction right in browser. It is written in PHP which could be bonus for PHP developers.
