I noticed that even that we have some documentation about the components that compose OS/2, there was not a single unified source with it.
So, some months ago I started to try to document the OS/2 components on the EDM/2 wiki under the Creative Commons Share Alike license. With that the documentation generated can be used for derivative works and since it is a wiki, more people can help me to complement it.
For the moment I started the "Components" category on the EDM/2 wiki: http://www.edm2.com/index.php/Category:Components
And I'm trying to put a little description of the OS/2 component and put the files that belongs that that components.
Also, on the DLL files I'm trying to put more information on the versions available, the DLL entry points, the other DLLs that this file calls and, if applies, to put if there is an open source alternative of it. At the end I'm putting all the files on this category: http://www.edm2.com/index.php/Category:Files
Let see how this documentation evolves over time and if it can be useful for developers on the future.
