"""
parser.http.searchPersonParser module (imdb package).

This module provides the HTMLSearchPersonParser class (and the
search_person_parser instance), used to parse the results of a search
for a given person.
E.g., when searching for the name "Mel Gibson", the parsed page would be:
    http://www.imdb.com/find?q=Mel+Gibson&nm=on&mx=20
