Sometimes its just dumb luck, or being in the right place at the right time. Convert::TNEF was my first module, and I was most definitely NOT an expert at writing perl modules, and only somewhat competent at perl. But I was the first one to find all the proper docs on TNEF and the desire and need to put it all together in a module (I've since heard from others (w/more perl experience) who said they tried to do the same thing in the past but just couldn't find enough info on TNEF).

<tongue-in-cheek>BTW, if IlyaM(above) ever gets a look at the code, he may decide not to use it because the indentation makes the code look truly horrid to most eyes</t-i-c> (it is consistent, but I was into one-space indentation at the time (lame excuse => sore thumb), and I've been meaning to run the whole thing through perltidy for awhile now :)
But then again, using that sort of logic, anyone looking at the CGI code may decide not to use it :-)

Update: Don't worry IlyaM, with any luck, you'll never have to use it :)
