Wow, talk about cheap thrills :)
Doesn't the German keyboard have a "/" key over the number 8 on the
numpad (that is if you are not using a laptop)?

The pdmtl abstractions REQUIRE that you keep the folder prefix. The
prefix IS part of the abstraction's name. But this is not a problem
because it takes as long to type list/whatever than list-whatever.

I created a version of list/abs in our svn repository. It works just
fine. I do not understand what is impossible?

This is definitely ridiculous. Tthe pdmtl abstractions installation
instructions require one line of text to be added to the path and
another as a startup flag. We are currently working on adding these by
default to pd-extended.

Once both lines are added to pd's configuration everything works
great. Even the help files. However, creating an abstraction with
[pdmtl/list/op] is not recommended. The same goes for creating a
[cyclone/counter]. Instancing in this fashion in simply too long
(while you simply had to add cyclone to your path) and breaks
compatibility with other people's distributions (for example people
that use the cylone.pd_linux instead of the expanded folder or
whatever it is called).
