Actionpoll is a simple PHP script which provides the standard functionality such as unlimited options, IP tracking of users, easy installation, and HTML and WML output. An event can be triggered if a certain number of votes is reached. Surveys can be stored either in a MySQL database or in text files.
AFT (Almost Free Text) is a document preparation system. It is mostly free form, meaning that there is little intrusive markup; AFT source documents look a lot like plain old ASCII text. It has a few rules for structuring your document, more to do with formatting your text than embedding lots of commands, and it produces all types of output (HTML, XHTML, LaTeX, roll-your-own XML, etc.). All that needs to be done is to edit a rule file. You can even customize your own rule files for specialized output.
