parser.http.movieParser module (imdb package).

This module provides the classes (and the instances), used to parse the
IMDb pages on the akas.imdb.com server about a movie.
E.g., for Brian De Palma's "The Untouchables", the referred
pages would be:
    combined details:   http://akas.imdb.com/title/tt0094226/combined
    plot summary:       http://akas.imdb.com/title/tt0094226/plotsummary
    ...and so on...
