The following ZIP file is an entire PL/SQL application framework and documentation that could give your custom Oracle application a boost by several months.

Have no fear. There are only ascii text files in here ;-)

Read the included User Guide in the Docs directory. The Getting Started and Installation sections should help. I routinely install the whole thing in under 2 minutes.
