-If a
-.I header-field-name
-is supplied using the
-.B -attach
-option, the draft is scanned for a header whose field name matches the
-supplied
-.IR header-field-name .
-The draft is converted to a MIME message if one or more matches are found.
-This conversion occurs before all other processing.
-.PP
-The first part of the MIME message is the draft body if that body contains
-any non-blank characters.
-The body of each header field whose name matches the
-.I header-field-name
-is interpreted as a file name, and each file named is included as a separate
-part in the MIME message.
-.PP
-For file names with dot suffixes, the context is scanned for a
-.I mhshow-suffix-
-entry for that suffix.
-The content-type for the part is taken from that context entry if a match is
-found.
-If no match is found or the file does not have a dot suffix, the content-type
-is text/plain if the file contains only ASCII characters or application/octet-stream
-if it contains characters outside of the ASCII range.
-.PP
-Each part contains a name attribute that is the last component of the path name.
-A
-.I x-unix-mode
-attribute containing the file mode accompanies each part.
-Finally, a description attribute is generated by running the
-.I file
-command on the file.
-.PP
-The
-.B -attachformat
-option specifies the MIME header field formats: a value of
-.B 0,
-the default,
-includes the
-.I x-unix-mode
-attribute as noted above. A value of
-.B 1
-suppresses both that and the \*(lqContent-Description\*(rq header, and
-adds a \*(lqContent-Disposition\*(rq header. A value of
-.B 2
-adds the file
-.I modification-date
-parameter to the \*(lqContent-Disposition\*(rq header. You can
-specify one value in your profile, and override it for individual
-messages at the
-.I whatnow
-prompt.

-Here are example message part headers, for an attachment, for each of the
-.B -attachformat
-values:

+Unless a
+.I MIME-Version
+header is already present, the message is converted to a MIME message.
+In this process, the draft is scanned for attachment header fields.
+Their name defaults to ``Attach'', but may be changed by the value of the
+.I Attachment-Header
+profile entry.
+If such header fields are found, the body of each is interpreted as a
+file name (or a message specification), and each of these files or
+messages is included as a separate part in the MIME message.
+(The first part of the MIME message is the draft body.)

+The MIME type of each file is determined by the MIME type query program,

+The last component of the path name is taken as the name of the MIME parts.
