"The installation procedure has changed significantly since version 2.0 of "
"MagicUserInterface. Instead of spreading the MUI related files all "
"over your system, one single MUI directory will be created at some place "
"of your choice. This directory will hold all necessary programs and "
"libraries for a complete MUI installation. Depending on the available "
"space on your harddisk, you may decide to install additional "
"demonstration programs, documentation material and images."
