.B mhbuild
input file.
-.SS "Listing the Contents"
-The
-.B \-list
-switch tells
-.B mhbuild
-to list the table of contents associated with the MIME message that is created.
-.PP
-The
-.B \-headers
-switch indicates
-that a one-line banner should be displayed above the listing. The
-.B \-realsize
-switch tells
-.B mhbuild
-to evaluate the \*(lqnative\*(rq
-(decoded) format of each content prior to listing. This provides an
-accurate count at the expense of a small delay. If the
-.B \-verbose
-switch
-is present, then the listing will show any \*(lqextra\*(rq information
-that is present in the message, such as comments in the
-\*(lqContent-Type\*(rq header.

-There are four kinds of directives: \*(lqtype\*(rq directives, which
-name the type and subtype of the content; \*(lqexternal-type\*(rq
-directives, which also name the type and subtype of the content; the
-\*(lqmessage\*(rq directive (#forw), which is used to forward one or
-more messages; and, the \*(lqbegin\*(rq directive (#begin), which is
-used to create a multipart content.
+There are three kinds of directives:
+\*(lqtype\*(rq,
+\*(lqmessage\*(rq (#forw),
+and \*(lqbegin\*(rq (#begin).
.PP
-The \*(lqtype\*(rq directive is used to directly specify the type and
+.B "(1) The \*(lqtype\*(rq directive
+is used to directly specify the type and
subtype of a content. You may only specify discrete types in this manner
(can't specify the types multipart or message with this directive).
You may optionally specify the name of a file containing the contents
environment variable, instead of directly in your
user profile.
.PP
-The \*(lqexternal-type\*(rq directives are used to provide a MIME
-reference to a content, rather than enclosing the contents itself
-(for instance, by specifying an ftp site). Hence, instead of
-providing a filename as with the type directives, external-parameters
-are supplied. These look like regular parameters, so they must be
-separated accordingly. For example,
-.PP
-.RS 5
-.nf
-#@application/octet-stream; \\
- type=tar; \\
- conversions=compress \\
- [this is the nmh distribution] \\
- {application; filename="nmh.tar.gz"} \\
- name="nmh.tar.gz"; \\
- directory="/pub/nmh"; \\
- site="ftp.math.gatech.edu"; \\
- access-type=anon-ftp; \\
- mode="image"

-You must give a description string to separate the content parameters
-from the external-parameters (although this string may be empty).
-This description string is specified by enclosing it within
-\*(lq[]\*(rq. A disposition string, to appear in a
-\*(lqContent-Disposition\*(rq header, may appear in the optional
-\*(lq{}\*(rq.

+is used to specify a message or
group of messages to include. You may optionally specify the name of
the folder and which messages are to be forwarded. If a folder is not

For example,
.PP
.RS 5
will add a content of type \*(lqmultipart/digest\*(rq
and include each message as a subpart of this content.
.PP
-If you are using this directive to include more than one message, you
-may use the
-.B \-rfc934mode
-switch. This switch will indicate that
-.B mhbuild
-should attempt to utilize the MIME encapsulation rules
-in such a way that the \*(lqmultipart/digest\*(rq that is created
-is (mostly) compatible with the encapsulation specified in RFC\-934.
-If given, then RFC\-934 compliant user-agents should be able to burst the
-message on reception\0--\0providing that the messages being encapsulated
-do not contain encapsulated messages themselves. The drawback of this
-approach is that the encapsulations are generated by placing an extra
-newline at the end of the body of each message.

When using the \*(lqbegin\*(rq directive, you must specify at least one

corresponding to each message part; however, the user may override
this by defining the ID using the \*(lq<\*(rq and \*(lq>\*(rq

-.SS "Integrity Check"
-If
-.B mhbuild
-is given the
-.B \-check
-switch, then it will also associate
-an integrity check with each \*(lqleaf\*(rq content. This will add a
-Content-MD5 header field to the content, along with the md5 sum of the
-unencoded contents. This may be used by the receiver of the message to
-verify that the contents of the message were not changed in transport.
.SS "Transfer Encodings"
After
which transfer encoding to use. It will check for 8bit data, long lines,
spaces at the end of lines, and clashes with multipart boundaries. It will
then choose a transfer encoding appropriate for each content type.
-.PP
-If an integrity check is being associated with each content by using
-the
-.B \-check
-switch, then
-.B mhbuild
-will encode each content with
-a transfer encoding, even it the content contains only 7\-bit data. This
-is to increase the likelihood that the content is not changed while in
-transport.
-.PP
-The switch
-.B \-ebcdicsafe
-will cause
-.B mhbuild
-to slightly change
-the way in which it performs the \*(lqquoted-printable\*(rq transfer
-encoding. Along with encoding 8\-bit characters, it will now also encode
-certain common punctuation characters as well. This slightly reduces the
-readability of the message, but allows the message to pass more reliably
-through mail gateways which involve the EBCDIC character encoding.
.SS "Invoking mhbuild"
Typically,
.B mhbuild
- is invoked by the
-.B whatnow
-program. This
-command will expect the body of the draft to be formatted as an

.PP
-prior to sending the draft. This will cause
-.B whatnow
-to execute
-.B mhbuild
-to translate the composition file into MIME format.
-.PP
-It is also possible to have the
-.B whatnow
-program invoke
-.B mhbuild
-automatically when a message is sent. To do this, you must add the line
-.PP
-.RS 5
-automimeproc: 1

-to your
-.I .mmh/profile
-file.
-.PP
-Finally, you should consider adding this line to your profile:

-This way, if you decide to
-.B list
-after invoking
-.BR mime ,
-the command

-What now? list

+.SH BUGS
+Outlook 2002 won't display attachments that have a Content-ID header.
+This is a bug in Outlook 2002, not in
+.BR mhbuild .
+To workaround it, invoke \fIe mhbuild\fP manually at the Whatnow prompt
+and edit the draft again thereafter, removing the Content-ID headers.
+Then send it.
+There used to be a
+.B \-nocontentid
+switch to prevent Content-ID headers to be inserted, but as it was considerd
+wrong to complicate all other MUAs instead of forcing the developers and users
+of broken MUAs to fix or change their software, it was removed.
