Unix validation tools - How you can help

The program behaviour differs in some (I hope, not so important) details from the originals. Some options, exit values and manual descriptions I did not completely understand (may be, I'm too stupid ;-), that's why I implemented them in order to match my expectations. The messages are not exactly the same as in the originals. I tried to correct some missunderstandable parts. I hope I did not create new errors ;-)

So: How you can help?

If you think, you should write me (even if it's not to the topics mentioned above) - do it. You can find my mail address on my contact page.
