+/* Information:
+ * This class implements a mechanism to lock a users installation directory,
+ * which is necessary because instances of staroffice could be running on
+ * different hosts while using the same directory thus causing data
+ * inconsistency.
+ * When an existing lock is detected, the user will be asked whether he wants
+ * to continue anyway, thus removing the lock and replacing it with a new one
+ *
+ * ideas:
+ * - store information about user and host and time in the lockfile and display
+ * these when asking whether to remove the lockfile.
+ * - periodically check the lockfile and warn the user when it gets replaced
