28 @chapter What is SEMI?
30 SEMI is a package for GNU Emacs to provide features related with MIME
31 user interface.@refill
33 SEMI provides two user interfaces: MIME-View and MIME-Edit.@refill
36 MIME-View is a kernel of user interface to display or operate MIME
37 messages, STD 11 messages or ``localized RFC 822'' messages.@refill
39 MIME-Edit is a user interface to compose MIME messages.@refill
41 Each MUA can use powerful MIME features to combine these features.

128 How to compose MIME message in MIME-Edit mode.
130 C-c C-x ? shows its help.
132 C-c C-x C-t insert a text message.
133 C-c C-x TAB insert a (binary) file.
134 C-c C-x C-e insert a reference to external body.
135 C-c C-x C-v insert a voice message.
136 C-c C-x C-y insert a mail or news message.
137 C-c C-x RET insert a mail message.
138 C-c C-x C-s insert a signature file at end.
139 C-c C-x t insert a new MIME tag.
140 C-c C-x a enclose as multipart/alternative.
141 C-c C-x p enclose as multipart/parallel.
142 C-c C-x m enclose as multipart/mixed.
143 C-c C-x d enclose as multipart/digest.
144 C-c C-x s enclose as PGP signed.
145 C-c C-x e enclose as PGP encrypted.
146 C-c C-x C-k insert PGP public key.
147 C-c C-x C-p preview editing MIME message.
150 therefore, you should type C-c C-x C-i and specify the binary file
151 which you want to insert.
153 You should select Base64 as MIME encoding for binary file.
159 Like above, you can compose the message with image.

206 File name for uuencode'ing
210 If none of them are specified, displays a blank.
212 The 3rd item in the parenthesis describes media-type/subtype of
213 the entity. If it is is not MIME entity, it displays @code{nil}.
216 This entity-button plays a role like icon that symbolically
217 shows the content of the entity. For example, push @kbd{v} on

579 @node transfer level, message/partial sending, file-type specification, MIME-Edit
580 @section transfer level
581 @cindex transfer level
583 Each content inserted in a message is represented by 7bit
584 (@ref{(mime-en)7bit}), 8bit (@ref{(mime-en)8bit}) or binary
585 (@ref{(mime-en)binary}).@refill
587 If a message is translated by 7bit-through MTA (@ref{(mime-en)MTA}),
588 there is no need to encode 7bit data, but 8bit and binary data must be
589 encoded to 7bit data.@refill
591 Similarly, if a message is translated by 8bit-through MTA, there is no
592 need to encode 7bit or 8bit data, but binary data must be encoded to
593 7bit or 8bit data.@refill
598 EBCDIC MTA breaks 7bit data, so in this case, 7bit data must be
599 encoded by base64. But I don't know EBCDIC. (^_^;
601 Similarly, I wish ASCII-printable only MTA and code-conversion MTA
602 disappeared. (^_^;@refill
604 Maybe there are binary-through MTA, but I think it is not major.
607 @strong{transfer level} represents how range data are
608 available. mime-edit has a variable @code{mime-transfer-level}
609 to represent transfer level.
612 @defvar mime-transfer-level
614 transfer level.@refill
616 If transfer level of a data is over it, a data is encoded to
619 Currently, 7 or 8 is available. Default value is 7.@refill
621 In extension plan, EBCDIC will be 5, ASCII printable only will be 6,
622 binary will be 9. But it will not be implemented.
630 transfer level is only for body, not for message header (@ref{header}).
631 MIME extends RFC 822 (@ref{(mime-en)RFC 822}) to use 8bit data in body,
632 but it requires to use us-ascii (@ref{(mime-en)us-ascii}) in header.

656 If it is not specified for a major-mode,
