-    //           is not set
-    //        2) it doesn't look into ~/.kde/share/config/kdeglobals where
-    //           user's settings are stored and thus *ignores* user's settings
-    //           instead of respecting them
-    //        3) it "tries to guess KDEDIR" and "tries a few likely theme
-    //           names", both of which is completely arbitrary; instead, the
-    //           code should give up if KDEDIR(S) is not set and/or the icon
