subtype, separate the two with a slash, e.g., \*(lqaudio/basic\*(rq.
Note that regardless of the values given to the `\-type' switch, a
multipart content (of any subtype listed above) is always acted upon.
-Further note that if the `\-type' switch is used, and it is desirable to
-act on a message/external-body content, then the `\-type' switch must
-be used twice: once for message/external-body and once for the content
-externally referenced.
.SS "Unseen Sequence"
If the profile entry \*(lqUnseen\-Sequence\*(rq is present and
non\-empty, then
.B mhshow
will remove each of the messages shown
from each sequence named by the profile entry.
-.SS "Checking the Contents"
-The
-.B \-check
-switch tells
-.B mhshow
-to check each content for an
-integrity checksum. If a content has such a checksum (specified as a
-Content-MD5 header field), then
-.B mhshow
-will attempt to verify the
-integrity of the content.
.SS "Showing the Contents"
The headers of each message are displayed with
.B mhl
.PP
If none of these apply, then
.B mhshow
-will check to see if the message
-has an application/octet-stream content with parameter \*(lqtype=tar\*(rq.
-If so,
-.B mhshow
-will use an appropriate command. If not,
-.B mhshow
will complain.
.PP
Example entries might be:
.PP
Finally,
.B mhshow
-will process each message serially\0--\0it won't start
+will process each message serially \- it won't start
showing the next message until all the commands executed to display the
current message have terminated. In the case of a multipart content
(of any subtype listed above), the content contains advice indicating if
the parts should be displayed serially or in parallel. Because this may
-cause confusion, particularly on uni-window displays, the
-.B \-serialonly
-switch can be given to tell
+cause confusion, particularly on uni-window displays,
.B mhshow
-to never display parts in parallel.
+will never display parts in parallel.
.SS "Showing Alternate Character Sets"
Because a content of type text might be in a non-ASCII character
set, when
.BR mhstore (1)
for details.
.SS "External Access"
-For contents of type message/external-body,
-.B mhshow
-supports these access-types:
-.PP
-.IP \(bu 4
-afs
-.IP \(bu 4
-anon-ftp
-.IP \(bu 4
-ftp
-.IP \(bu 4
-local-file
-.IP \(bu 4
-mail-server
-.PP
-For the \*(lqanon-ftp\*(rq and \*(lqftp\*(rq access types,
-.B mhshow
-will look for the \*(lqnmh-access-ftp\*(rq
-profile entry, e.g.,
-.PP
-.RS 5
-nmh-access-ftp: myftp.sh
-.RE
-.PP
-to determine the pathname of a program to perform the FTP retrieval.
-.PP
-This program is invoked with these arguments:
-.PP
-.RS 5
-.nf
-domain name of FTP-site
-username
-password
-remote directory
-remote filename
-local filename
-\*(lqascii\*(rq or \*(lqbinary\*(rq
-.fi
-.RE
-.PP
-The program should terminate with an exit status of zero if the
-retrieval is successful, and a non-zero exit status otherwise.
-.SS "The Content Cache"
-When
-.B mhshow
-encounters an external content containing a
-\*(lqContent-ID:\*(rq field, and if the content allows caching, then
-depending on the caching behavior of
-.BR mhshow ,
-the content might be read from or written to a cache.
-.PP
-The caching behavior of
-.B mhshow
-is controlled with the
-.B \-rcache
-and
-.B \-wcache
-switches, which define the policy for reading from,
-and writing to, the cache, respectively. One of four policies may be
-specified: \*(lqpublic\*(rq, indicating that
-.B mhshow
-should make use
-of a publically-accessible content cache; \*(lqprivate\*(rq, indicating
-that
-.B mhshow
-should make use of the user's private content cache;
-\*(lqnever\*(rq, indicating that
-.B mhshow
-should never make use of
-caching; and, \*(lqask\*(rq, indicating that
-.B mhshow
-should ask the user.
-.PP
-There are two directories where contents may be cached: the profile entry
-\*(lqnmh-cache\*(rq names a directory containing world-readable contents, and,
-the profile entry \*(lqnmh-private-cache\*(rq names a directory containing
-private contents. The former should be an absolute (rooted) directory
-name.
-.PP
-For example,
-.PP
-.RS 5
-nmh-cache: /tmp
-.RE
-.PP
-might be used if you didn't care that the cache got wiped after each
-reboot of the system. The private cache is interpreted relative to the user's
-mail storage, if not rooted, e.g.,
-.PP
-.RS 5
-nmh-private-cache: .cache
-.RE
-.PP
-(which is the default value).
+.B Mhshow
+does not automatically retrieve message/external-body parts (anymore),
+but prints the relevant information to enable the user to retrieve
+the files manually.
.SS "User Environment"
Because the display environment in which
.B mhshow
^Path:~^To determine the user's mail storage
^Current\-Folder:~^To find the default current folder
^Unseen\-Sequence:~^To name sequences denoting unseen messages
