I'm all for using regex patterns, as you have done in the second line
there, over simple globbing.

I think it would really depend on how much Cameron wants to build
into the crawler, and how much in the way of resources it would

Should there also use an order too, or have it assumed and hard-coded?


Order: allow, disallow
Allow: *
Disallow: */cache/*
Disallow: */history/*
