The OS/2 API Project

The OS/2 API Project (also known as The OS/2 API Documentation Project) is an effort that aims to document all the OS/2 available APIs under an non-restrictive license that can allow derivative works.

For contributors, please review the Introduction to the OS/2 API Documentation.
