Some poking around reveals
http://git.trinitydesktop.org/cgit/tdelibs/tree/tdecore/README.kiosk
which seems to be our equivalent of the source material for that page. It includes some
dcop-related discovery instructions.
In addition to the README.kiosk, the file
tde/main/applications/kiosktool/kiosktool/kiosk_data.xml defines the actions available in
kiosk and a short description of each of them. Search for "action type=" to get
a list of the supported actions.
