Currently I do not really plan to extend this program, as it does exactly what I want it to do, in a reasonably fast way.
Missing keywords for Java and C++ should be included sometimes. This mostly depends on someone sending me updated keyctionaries.
The manual should get some sections describing some internals, what tools can be useful together with vahunz and some ideas to extend the general concept of vahunzation which are beyond this particular utility.
Obvious extensions could be to support other programming languages. However, this would make the source much more error prone, so at the moment I do not think this is a good idea. But I suppose Oberon, Modula-2 and Pascal will be supported sometimes - if there is any interest.
Another feature could be to display some statistics about how many names have been replaced etc.; but nobody really cares about that, so it's something for a rainy weekend.

DEBUG=LINE, resulting in a shorter binary.
--quiet has -q as short form.
