pldoc is an open-source utility for generating HTML documentation of code written in Oracle PL/SQL. The goal is to provide a tool analogous to javadoc for Java.
The PLDoc source code on github was once fetched from the original pldoc project located at sourceforge, http://pldoc.sourceforge.net. The branch was made when I wanted to make some bigger changes, and needed a place to work. Hey, nothing beats github for that!
