This script acts like a one time {strip} tag, removing all unnecessary white spaces from your .html files generated by the HTML Catalog, thus reducing the bandwidth needed for these files.
At the moment, I don't have a .tpl interface written for it, so you have to call it from your browser. This works on your existing catalog, though I am sure you could pull out the regex code and stick it into admin/html_catalog.php if your so inclined.
Here is the code. Put it in whatever directory you wish under whatever name you wish (.php extension of course)...
