Oh boy, what have I taken on?
Going deeper and deeper into any documentation I can find about how one goes about source indexing. I have no idea what I've signed up for.
In my C:\Program Files\Debugging Tools for Windows\sdk\srcsrv directory there is an excellent source server document that walks through the steps and for the moment all I know is that I'll be needing Perl.
So I'm downloading ActivePerl as I write this and hopefully once it's installed I can chip away at setting up some indexing scripts.
