Well, it seems the script builder acts like a kind of documentation system,
like the "function wizard" in open office.

Since I'm interested in scripting with kstars, I did a small search about KDE scripting.
At Amarok for example, they have kept a subset of their old d-bus scripting and
added a javascript api based on QtScript framework[0]. Others seem to use QtScript too,
like plasma for writing plasmoids and controlling the desktop. On the other hand, there is
smoke(seems to export much of kde api) and kross(not for stand alone scripts?)
that support many languages, like python and ruby.

Out of curiosity, I followed the QT scripting guide[1], and made an example of how
one could use a supposedly existing kstars javascript api to make a simple calculation.
I'm attaching the files to see for yourselves.

Also, I've been looking at the kstars/INDI docs and there are references[2] about INDI scripts
for controlling devices, even with the help of script builder[3].
I have not been able to find a reference of how a script like that could look like, though ...
Just some commented out INDY functions in kstars.h

Cheers!
Yiannis
