/*************************************************************
 
This script will let you create a static copy of a bamboo site
as rendered html. This copy is then completely stand alone and 
does not need bamboo to be viewed or browsed.

USAGE:
   staticcopy --src /var/www/mysite --dest /var/www/mycopy

CAVEATS:
   - the site can't have multiple decorators
   - the decorator must include the stylesheet in each page
     statically if $robot is true (use stylesheet() function).
   - decorator images must be in the decorator folder, not
     in a subfolder. 

NOTES: 
  we only need to include the stylesheet in each page
  because of possible images in the stylesheet and our need
  to use all relative urls. if it doesn't have any images
  in the stylesheet, we might as well  use a common style.css
  for all pages.
