you source the script to define the namespace and its functions
and then the selftest proc can be seen as an example use.
you'll have to do a little Tcl scripting of yourself to use the

adjustment to be compatible with the latest version of tachyon.

if you need any explanation beyond that, you'll have to
upgrade your knowledge of Tcl. it is hard to modify
Tcl without knowing it. a good starting point for learning
more about Tcl is here:
