Do you have a link to the code?
The only link I could find
https://sites.google.com/site/copsfb...attredirects=0 seems to be dead.
What this piece of software seems to do is convert FBreader files to epub/mobi files on-the-fly. It does
not add a downloadable copy of a FBreader-file in epub-format to COPS. You can (only) do that with Calibre.
