How this program works in Prolog?

Given a program in Prolog. Please explain how it works?

count(X,[X|L],N):-count(X,L,N2),N is N2 + 1.

p([X|V],N,[X|L]):-count(X,[X|V],K),K >= N, delete(V,X,V2) p(V2,N,L).

p([X|V],N,L):-delete(V,X,V2) p(V2,N,L).

This program deletes from the input list all the elements that occur in the list more than N times.
