- * The -C option sets the MIME charset attribute for text/plain content.
- * The -N option sets the name attribute for Content-Type:
- * Encoding must be one of the following: 7bit, 8bit, quoted-printable, or base64.
-
- * -m multipart/TYPE: create a multipart MIME collection with Content-Type: multipart/TYPE

- * Type must be either "multipart/mixed", "multipart/alternative", or some other MIME multipart content type.
- * Additionally, encoding can only be "7bit" or "8bit", and will default to "8bit" if not specified.
- * Finally, filename must be a MIME-formatted section, NOT a regular file.
- * The -m option creates an initial multipart MIME collection, that contains only one MIME section, taken from filename.
- * The collection is written to standard output, or the pipe or to outputfile.
