It is probably a good indication of the worthiness (or in some cases the worthlessness) of the file if they posted back in 2002 without any documentation.
If you need a HTML file report, doesn't the unified reporting in WinRunner do that for you now? I can't answer as I don't use it and went the route of creating out reports from scratch in our own defined format, converting it to html later through PERL
Glad to hear you've taken some initiative and looked into what it gave you.
It still doesn't mean it is good thing to use. It was posted over 3 -4 years ago, with no documentation. This means that you are on your own if you want to use it, the person that origianlly posted it isn't around anymore (more than likely), and without them having posted documentation for it, you are going to either have to perform trial and error on it and see what you get, or drop it.
If there isn't documentation for it on the site (as you have pointed out a couple of times now), then how are any of the rest of us going to know what it does? Oh hang on! Let me get out my swami hat and crystal ball - I'll get back with you in a little while once I read the bones on this one!
