Today I finished PawnDoc 0.1. You may download PawnDoc at the official PawnDoc wiki page.
The tool PawnDoc is a tool for the Pawn language similar to JavaDoc for Java. With pawndoc-comments in your pawn sourcecode you can generate documentation-html-files and even wiki-syntax! See dprop.inc.wiki.txt or dprop.inc.html as example (source .pwn).
You can also find a welcome post at samp forums. PawnDoc is written in Lua 5.1.
