+ -e encoding - use the given encoding (7bit, 8bit, quoted-printable,
+ or base64), instead of guessing. Omit "-e" and use
+ -c auto to set Content-Type: to text/plain or

+
+ * -c TYPE: create a (non-multipart) MIME section with Content-Type: TYPE
+ * makemime -c TYPE [-e ENCODING] [-o OUTFILE] [-C CHARSET] [-N NAME] [-a HEADER...] FILE
+ * 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
+ * makemime -m multipart/TYPE [-e ENCODING] [-o OUTFILE] [-a HEADER...] FILE
+ * 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.
+
+ * -j FILE1: add a section to a multipart MIME collection
+ * makemime -j FILE1 [-o OUTFILE] FILE2
+ * FILE1 must be a MIME collection that was previously created by the -m option.
+ * FILE2 must be a MIME section that was previously created by the -c option.
+ * The -j options adds the MIME section in FILE2 to the MIME collection in FILE1.
