class HTMLHelp:
    """
    This class encapsulates support for HTML Help. Node names,
    file names, menu items, index items, and image file names are
    accumulated until a call to finalize(). At that time, three
    output files are created in the current directory:

        `helpbase`.hhp  is a HTML Help Workshop project file.
                        It contains various information, some of
                        which I do not understand; I just copied
                        the default project info from a fresh
                        installation.
        `helpbase`.hhc  is the Contents file for the project.
        `helpbase`.hhk  is the Index file for the project.

    When these files are used as input to HTML Help Workshop,
    the resulting file will be named:

        `helpbase`.chm

    If none of the defaults in `helpbase`.hhp are changed,
    the .CHM file will have Contents, Index, Search, and
    Favorites tabs.
