I'm afraid that archive.org just archives the resulting page and in 
general won't have the backend code (unless the site (um.mendelu.cz) 
somehow exposed the backend via something like http://...../*.php

The only other way would be to contact the people at mendelu.cz, or 
reverse-engineer it. A simple, "just for yourself" version would just do 
a pipe to a local maxima process, but of course an Internet-accessible 
version has to block commands that would damage your system 
(writefile("/home/eduardo/importantdata") or infinite-loop commands that 
would exhaust CPU/disk/memory).
