Natural Docs is an open-source documentation generator for multiple programming languages. You document your code in a natural syntax that reads like plain English. Natural Docs then scans your code and builds high-quality HTML documentation from it.

Natural Docs has full support for ActionScript 2 and 3, is now compatible with JavaDoc documentation.

Since the addition of ActionScript 2 support to NaturalDocs following the successful campaign on FlashAnt, members of the Flash community were quick to create GUIs for NaturalDocs. These are:

• NaturalGui: .Net front-end for NaturalDocs by Daniel Aguilar
• ac NaturalDocs Generator: JSFL extension for Flash by Greg Wygonik. Allows you to run NaturalDocs on code in your FLAs.
• NaturalGui Java Edition: Open source front-end for Natural Docs written in Java by Richard Leggett
• NaturalDocsSEPY: A batch file by Mark Walters that allows NaturalDocs to be used from within SEPY
