1 ADD
   Format: ADD filename

   When editing a message draft or new message, this command attaches
   the specified file to the current message.  MIME maintains a list of 
   known file types associated with various file name extensions; for 
   example, files that end in ".TXT" are treated as text. Use the 
   SHOW FILE_TYPES command to display this list of file types. To 
   override the default file type associated with any file, use one 
   of the ADD command qualifiers.

2 /BINARY
   Sets Content-Type to "application/octet-stream" and 
   Content-Transfer-Encoding to "Base64".  This format can 
   be used to represent an arbitrary binary data stream.

2 /CONTENT_TYPE
   /CONTENT_TYPE="type/subtype"

   Overrides the default Content-Type and sets it to the specified type 
   and subtype (enclosed in quotation marks). See RFC 1700 for a list of 
   registered media types and subtypes. Examples of types include text, 
   image, message, application, audio, and so forth. Subtypes specify 
   the type of content, such as jpg, bmp, gif, html, or plain.

2 /ENCODING
   /ENCODING_TYPE=encoding-type

   Overrides the default Content-Transfer-Encoding and sets it to the
   specified type.  Permissible types are:  7Bit, 8Bit, Base64, or 
   Quoted-Printable.

   Experimentation may be necessary to achieve the desired result.
   However, it is suggested to use Base64 for most binary files, 
   such as JPG and GIF image files. 

2 /MESSAGE
   Sets Content-Type to "message/rfc822", indicating that the 
   attachment contains the text of a message to be forwarded as an 
   attachment. Content-Transfer-Encoding for the attachment is 
   set to 7Bit.

2 /TEXT
   Sets Content-Type to "text/plain" and sets Content-Transfer-Encoding 
   to 7Bit.

2 Example
   MIME> add /content_type ="image/gif" /encoding=base64 filename.gif

   This adds an "IMAGE" attachment with a subtype of "GIF" using an
   encoding scheme of "BASE64" for the "filename.gif" file. Use the
   SHOW FILE_TYPES command to display the list of file types and their
   settings. 

3 Example
   MIME> add myfile.txt

   This would add the file "myfile.txt" with the default settings
   specified by the program and also any found in the file
   MIME$FILETYPES.DAT file. The current default settings for a text
   (.TXT) file are: the content type set to "text/plain;" with a
   content type parameter of "charset=ISO-8859-1" and an encoding of
   "7bit/8bit". Use the SHOW FILE_TYPES command to display the list of
   file types and their settings.
