net-mail/mailbase: document mailcap better
Also fix quoting of %s, and add %{charset} support to html.
Clean up the mailcap man page to generalize and remove mention of the
"metamail" package since this file is not specific to it.

.SH NAME

+mailcap - mail capabilities file
.SH DESCRIPTION
The
.I mailcap
-file is read by the
-.I metamail
-program to determine how to display non-text at the local site.
+file is read by e-mail clients to determine how to display non-text at the
local site.
The syntax of a mailcap file is quite simple, at least compared to termcap
files. Any line that starts with "#" is a comment. Blank lines are ignored.
Otherwise, each line defines a single mailcap entry for a single content type.
Long lines may be continued by ending them with a backslash character, \\.
-Each individual mailcap entry consists of a content-type specification, a
command to execute, and (possibly) a set of optional "flag" values. For
example, a very simple mailcap entry (which is actually a built-in default
behavior for metamail) would look like this:

can be used to indicate that the output of the 'cat' command may be
voluminous, requiring either a scrolling window, a pager, or some other
appropriate coping mechanism.
-The "type" field (text/plain, in the above example) is simply any legal
content type name, as defined by informational RFC 1524. In practice, this is
almost any string. It is the string that will be matched against the
"Content\-type" header (or the value passed in with \-c) to decide if this is
the mailcap entry that matches the current message. Additionally, the type
field may specify a subtype (e.g. "text/ISO\-8859\-1") or a wildcard to match
all subtypes (e.g. "image/*").

field may specify a subtype (e.g. "text/ISO\-8859\-1") or a wildcard to match
all subtypes (e.g. "image/*"). Note that wildcards may only be specified in
the subtype (e.g. "*" or "*/*" do not work), and as the entire subtype (e.g.
"application/x-*" does not work).
-The "command" field is any UNIX command ("cat %s" in the above example), and
is used to specify the interpreter for the given type of message. It will be
passed to the shell via the system(3) facility. Semicolons and backslashes
within the command must be quoted with backslashes. If the command contains
"%s", those two characters will be replaced by the name of a file that contains
the body of the message. If it contains "%t", those two characters will be
replaced by the content-type field, including the subtype, if any. (That is,
if the content-type was "image/pbm; opt1=something-else", then "%t" would be
replaced by "image/pbm".) If the command field contains "%{" followed by a
parameter name and a closing "}", then all those characters will be replaced by
the value of the named parameter, if any, from the Content-type header. Thus,
in the previous example, "%{opt1}" will be replaced by "something-else".
Finally, if the command contains "\\%", those two characters will b
e replaced by a single % character. (In fact, the backslash can be used to
quote any character, including itself.)
+The "command" field is any UNIX command ("cat %s" in the above example), and

-If no "%s" appears in the command field, then instead of placing the message
body in a temporary file, metamail will pass the body to the command on the
standard input. This is helpful in saving /tmp file space, but can be
problematic for window-oriented applications under some window systems such as
MGR.

problematic for window-oriented applications under some window systems such as
MGR.
-Two special codes can appear in the viewing command for objects of type
multipart (any subtype). These are "%n" and "%F". %n will be replaced by the
number of parts within the multipart object. %F will be replaced by a series
of arguments, two for each part, giving first the content-type and then the
name of the temporary file where the decoded part has been stored. In
addition, for each file created by %F, a second file is created, with the same
name followed by "H", which contains the header information for that body part.
This will not be needed by most multipart handlers, but it is there if you
ever need it.

The "notes=xxx" field is an uninterpreted string that is used to specify the
name of the person who installed this entry in the mailcap file. (The "xxx"
may be replaced by any text string.)
The "test=xxx" field is a command that is executed to determine whether or not
the mailcap line actually applies. That is, if the content-type field matches
the content-type on the message, but a "test=" field is present, then the test
must succeed before the mailcap line is considered to "match" the message being
viewed. The command may be any UNIX command, using the same syntax and the
same %-escapes as for the viewing command, as described above. A command is
considered to succeed if it exits with a zero exit status, and to fail
otherwise.
-The "print=xxx" field is a command that is executed to print the data instead
of display it interactively. This behavior is usually a consequence of
invoking metamail with the "\-h" switch.

-The "textualnewlines" field can be used in the rather obscure case where
metamail's default rules for treating newlines in base64-encoded data are
unsatisfactory. By default, metamail will translate CRLF to the local newline
character in decoded base64 output if the content-type is "text" (any subtype),
but will not do so otherwise. A mailcap entry with a field of
"textualnewlines=1" will force such translation for the specified content-type,
while "textualnewlines=0" will guarantee that the translation does not take
place even for textual content-types.

-The "compose" field may be used to specify a program that can be used to
compose a new body or body part in the given format. Its intended use is to
support mail composing agents that support the composition of multiple types of
mail using external composing agents. As with the view-command, the compose
command will be executed after replacing certain escape sequences starting with
"%". In particular, %s should be replaced by the name of a file to which the
composed data is to be written by the specified composing program, thus
allowing the calling program (e.g. metamail) to tell the called program where
to store the composed data. If %s does not appear, then the composed data will
be assumed to be written by the composing programs to standard output. The
result of the composing program may be data that is NOT yet suitable for mail
transport -- that is, a Content-Transfer-Encoding may still need to be applied
to the data.

that is, a Content-Transfer-Encoding may still need to be applied to the data.
The "composetyped" field is similar to the "compose" field, but is to be used
when the composing program needs to specify the Content-type header field to be
applied to the composed data. The "compose" field is simpler, and is preferred
for use with existing (non-mail-oriented) programs for composing data in a
given format. The "composetyped" field is necessary when the Content-type
information must include auxiliary parameters, and the composition program must
then know enough about mail formats to produce output that includes the mail
type information, and to apply any necessary Content-Transfer-Encoding.
Conceptually, "compose" specifies a program that simply outputs the specified
type of data in its raw form, while "composetyped" specifies a program that
outputs the data as a MIME object, with all necessary Content-* headers already
in place.

.B needsterminal
-If this flag is given, the named interpreter needs to interact with the user
on a terminal. In some environments (e.g. a window-oriented mail reader under
X11) this will require the creation of a new terminal emulation window, while
in most environments it will not. If the mailcap entry specifies
"needsterminal" and metamail is not running on a terminal (as determined by
isatty(3), the \-x option, and the MM_NOTTTY environment variable) then
metamail will try to run the command in a new terminal emulation window.
Currently, metamail knows how to create new windows under the X11, SunTools,
and WM window systems.

.B copiousoutput
-This flag should be given whenever the interpreter is capable of producing
more than a few lines of output on stdout, and does no interaction with the
user. If the mailcap entry specifies copiousoutput, and pagination has been
requested via the "\-p" command, then the output of the command being executed
will be piped through a pagination program ("more" by default, but this can be
overridden with the METAMAIL_PAGER environment variable).
-.SH BUILT-IN CONTENT-TYPE SUPPORT
-The metamail program has built-in support for a few key content-types. In
particular, it supports the text type, the multipart and multipart/alternative
type, and the message/rfc822 types. This support is incomplete for many
subtypes -- for example, it only supports US-ASCII text in general. This kind
of built-in support can be OVERRIDDEN by an entry in any mailcap file on the
user's search path. Metamail also has rudimentary built-in support for types
that are totally unrecognized -- i.e. for which no mailcap entry or built-in
handler exists. For such unrecognized types, metamail will write a file with a
"clean" copy of the data -- i.e. a copy in which all mail headers have been
removed, and in which any 7-bit transport encoding has been decoded.
+This flag should be given whenever the interpreter is capable of producing

will be piped through a pagination program ("more" by default, but this can be
overridden with the PAGER environment variable).
