Yes, this is the right place.

For which keyboard layout did you create a XML description file? Chances are
it's interesting for more people than just you. If this is the case I would
like to include it in the KTouch distribution so everyone can benefit from
There is no script to generate lessons, see reasons below.

The 2.x series of KTouch--available since KDE 4.10--uses a new course and
keyboard layout file format. The old formats are really old and did carry lot
of cruft from the old pre-XML days.
The script you found generate lessons in the old format from a word list, but
the results are really poor. Not only the generated lessons are illegible
gibberish, but the script didn't even introduce new characters properly. Often
early lessons did contain letters from later lessons.
The scripts bundled with the new version can be used to convert keyboard
layout and course files from the old format to the new format.
So in theory you can use the old script to generate some lessons and convert
them to the new format, but that's not what I would recommend. Training on
real words and sentences is much more effective (and fun) than training on
random data. That's way I didn't bother to create a new course generation
Instead I rely on human-created lesson for KTouch. This obviously way more
work but I think the result is worth it.
