When I copy a website to my hard drive, httrack renames the files and rewrites
the contents.  For example, I'm trying to copy a site that names its file with
the .htm extension, rather than .html.  I want to leave it that way.  But all
of the copied files have been renamed to .html, and the files have been
rewritten so that the navigation points to these renamed files.  There is also
a comment added to the top of each page.

I want the pages copied EXACTLY as they are on the website.  How do I do that.
