Return a dictionary containing the mailcap database.

    The dictionary maps a MIME type (in all lowercase, e.g. 'text/plain')
    to a list of dictionaries corresponding to mailcap entries.  The list
    collects all the entries for that MIME type from all available mailcap
    files.  Each dictionary contains key-value pairs for that MIME type,
    where the viewing command is stored with the key "view".

Read a mailcap file and return a dictionary keyed by MIME type.

    Each MIME type is mapped to an entry consisting of a list of
    dictionaries; the list will contain more than one such dictionary
    if a given MIME type appears more than once in the mailcap file.
    Each dictionary contains key-value pairs for that MIME type, where
    the viewing command is stored with the key "view".

Find a match for a mailcap entry.

    Return a tuple containing the command line, and the mailcap entry
    used; (None, None) if no match is found.  This may invoke the

    entry to use.
