+//+ Name DwUuencode -- Class for performing uuencode or uudecode operations
+//+ Description
+//. {\tt DwUuencode} performs uuencode or uudecode operations.  Uuencode
+//. is a format for encoding binary data into text characters for transmission
+//. through the mail system.  The format also includes the file name and the
+//. file mode.  (Note: The file mode is significant only in UNIX.)  In MIME,
+//. the use of uuencode is deprecated; base64 is the preferred encoding
+//. for sending binary data.
+//.
+//. To use {\tt DwUuencode} for encoding binary data into uuencode format,
+//. set the file name, file mode, and binary data string using the member
+//. functions {\tt SetFileName()}, {\tt SetFileMode()}, and
+//. {\tt SetBinaryChars()}.  Then call the member function {\tt Encode()}.
+//. Finally, retrieve the uuencoded text characters by calling
+//. {\tt AsciiChars()}.
+//.
+//. To use {\tt DwUuencode} to decode uuencoded data, set the ASCII characters
+//. using the member function {\tt SetAsciiChars()}, then call {\tt Decode()}.
+//. Finally, retrieve the file name, file mode, and binary characters by
+//. calling {\tt FileName()}, {\tt FileMode()}, and {\tt BinaryChars()}.
