+# any other. So in case you have more +kdeprefix installs you can choose to
+# which one link in first place if is there.
+# @CODE
+# Acceptable values are:
+# stable = 4.1 or what so ever is main tree if nan choose testing by default
+# testing = what so ever is in testing on main tree
+# snapshot = 4.2 or what so ever is released under snapshots
