 Further Development
 -------------------
-While I've been successfully using 'tdv' for many years now, some issues
-should be addressed before including the software in regular Linux and/or
-BSD distributions:
-
- - The GUI is awkward to configure.
- - Lacking configuration, standard StarDict locations should be scanned.

-Given all issues with the file format, it might be better to start anew.
+Lacking configuration, standard StarDict locations should be scanned.
