William:  I tried that approach but it still takes forever.  Typically all the
posts of the blog are referred to in all the post pages so essentially the
number of cross-references goes as 2*n*n  if you have n pages to start with.

Needless to say that a 300-page blog would create 180,000 cross-referenced
files that would eventually get cleaned up but what a loss of time, space,
etc.

There's got to be a better way.  Maybe a simple option such as:  only download
and analyze once for each page title since one can assume that each page has a
different title in that case.

What do you think?Best,
