Unfortunately, I don't think that's possible. After all, the information has 
to be gathered comparing the textual output of "cmake --help-full". While most 
differences are pretty straightforward to interpret (at least for a human 
reader), sometimes the documentation changes and you really have to read the 
different versions and decide if there really was a change in behaviour, or if 
it's just a documentation change.

I don't have any time for this matter before next Thursday, but regarding the 
positive reactions on this list I will certainly complete the matrix.

Eric: I can send you the shell-scripts if you want to have a look...

Have a nice weekend,
