RP3 is not installed when 'KDE workstation' configuration is installed.
How am I supposed to configure my ISP connection now?
If I'm supposed to use kppp, by the way, it should have a more user-friendly
name in the menu (like 'Configure Dial-up Account').
kppp is the KDE equivalent of rp3, so that is the tool to use for configuring
ISP connections. I will forward the request for naming it something else to the
KDE development team.
