//+ Name DwBinhex -- Class for converting files to or from Binhex 4.0 format
//+ Description
//. {\tt DwBinhex} converts data to or from Binhex 4.0 format.  Binhex is a
//. format used almost exclusively on Macintosh computers for encoding
//. files into text characters for transmission through the mail transport
//. system or for archiving on non-Macintosh systems.  The format includes
//. the file name, file type, file creator, Macintosh Finder flags, data fork,
//. resource fork, and checksums. In MIME, the use of Binhex is deprecated;
//. applesingle and appledouble are the preferred format for encoding
//. Macintosh files.  The Binhex 4.0 format is described in RFC-1741.
//. Binhex is a widely used, {\it de facto} standard, but it is not an
//. official Internet standard.
//.
//. To use {\tt DwBinhex} for converting a Macintosh file to Binex format,
//. call the member functions {\tt SetFileName()}, {\tt SetFileType()},
//. {\tt SetFileCreator()}, {\tt SetFlag1()}, {\tt SetFlag2()},
//. {\tt SetDataFork()}, and {\tt SetResourceFork()} to set the elements
//. to be encoded.  Any elements that are not set by calling one of the
//. member functions are assigned reasonable defaults.  Then call the
//. {\tt Encode()} member function to actually perform the conversion to
//. Binhex.  Finally, call {\tt BinhexChars()} to retrieve the Binhex
//. characters.
//.
//. To use {\tt DwBinhex} for converting a Macintosh file from Binhex format,
//. call the member function {\tt SetBinhexChars()} to assign the Binhex
//. characters to be converted.  Then call {\tt Decode()} to actually
//. perform the conversion.  Finally, call {\tt FileName()}, {\tt FileType()},
//. {\tt FileCreator()}, {\tt Flag1()}, {\tt Flag2()}, {\tt DataFork()},
//. and {\tt ResourceFork()} to extract the decoded elements.
//.
//. Note: {\tt DwBinhex} does not change the file name in any way. When you
//. you are dealing with file names, you should be aware of the fact that
//. some filenames that are valid on a Macintosh may cause problems or
//. unexpected results on a non-Macintosh system, and vice versa.  Such
//. problem characters include slash ('/'), colon (':'), space and possibly
//. other characters.

    //. should be set as the data fork.

    //. on non-Macintosh systems, such as a GIF or JPEG file, the resource
    //. should be normally be empty.

    const DwString& BinhexChars() const;
    void SetBinhexChars(const DwString& aStr);
    //. Gets or sets the characters of the Binhex encoded file.

    void Encode();
    //. Converts the Macintosh file information to Binhex format.

    int Decode();
    //. Converts the Macintosh file information from Binhex format.  Returns
    //. zero if the decode operation completes successufully; otherwise,
    //. the function returns -1.
