This is a small, h2pas helped, translation of lubquvi headers for freepascal. libquvi allows extracting correct urls for videos served on various media pages. What its lacking ? Declare the external name of the functions (because pascal case rules creates name collisions with the standard names) and solve a small compiler warning that c style sets must be ordered ascending.
I am puting the code here because my hard disk is doing clicks and i fear losing it.
