%% mime_parse(+Data, -Parsed) is det.
%
% True when Parsed is a parsed representation of the MIME message
% in Data. Data is one of
%
% * stream(In)
% * stream(In, Length)
% * an Atom, String or list of characters.
%
% Parsed is a structure of this form:
%
% * mime(Attributes, Data, SubMimeList)
%
% Where Data is the (decoded) field data returned as an atom. If a
% part is of type =|text/...|=, the charset is interpreted as
% follows: if charset contains =|UTF-8|= or an alias thereof, the
% text is interpreted as UTF-8. If it the charset can be
% interpreted as ISO-8859-1 or US-ASCII, no conversion is applied.
% Otherwise, default locale specific conversion is applied. See
% also mime_default_charset/2.
%
% Attributes is a property-list and SubMimeList is a list of
% mime/3 terms reflecting the sub-parts. Attributes contains the
% following members:
%
% * id(Atom)
% Identifier of the message-part.
% * description(Atom)
% Descriptive text for the \arg{Data}.
% * language(Atom)
% Language in which the text-data is written.
% * md5(Atom)
% * type(Atom)
% Denotes the Content-Type, how the \arg{Data} should be interpreted.
% * character_set(Atom)
% The character set used for text data. See above.
% * transfer_encoding(Atom)
% How the \arg{Data} was encoded. This is not very
% interesting as the library decodes the content of the message.
% * disposition(Atom)
% Where the data comes from. The current library only deals
% with `inline' data.
% * filename(Atom)
% Name of the file the data should be stored in.
% * name(Atom)
% Name of the part.
%% mime_default_charset(-Old, +New) is det.
%
% True when Old reflects the old and new the new default character
% set of the library. The system default is =|us-ascii|=. This
% value is returned into the attribute =character_set= (see
% mime_parse/2) if the message does not explicitly specifythe
% character set. It is used for translating the message content.
%
% @bug This setting is global and shared between threads.
