Look at the original sample from +# the metamail distribution for more ideas. This is a simplified version +# to explain how it works with Pine. As of October, 1994, metamail was +# available via anonymous ftp from the host thumper.bellcore.com in the +# file /pub/nsb/mm2.7.tar.Z. +# +# Metamail is: +# Copyright (c) 1991 Bell Communications Research, Inc.

BELLCORE +# MAKES NO REPRESENTATIONS ABOUT THE ACCURACY OR SUITABILITY +# OF THIS MATERIAL FOR ANY PURPOSE. IT IS PROVIDED "AS IS", +# WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES. +# +# The mailcap viewers are used by Pine when viewing pieces of a message +# from within the attachment viewer. That is, you type the "V" command +# when already viewing a message. +# +# Pine expects the mailcap file to be in /etc/mailcap on Unix systems. +# Users may override or extend this with a .mailcap file in their home +# directory. The contents of that will be combined with /etc/mailcap. +# Users may override this standard Pine mailcap path +# ("~/.mailcap:/etc/mailcap") by defining the environment variable +# MAILCAPS to be equal to the colon separated path. +# +# On PC's (DOS or Windows) the file MAILCAP is searched for first in the +# same directory where the user's PINERC is located and then in the same +# directory where PINE.EXE is located. The first would be the user's personal +# override file and the second the common file used by all users. Users +# may override this location by defining the environment variable MAILCAPS +# to be equal to the *semicolon* separated path. +# +# Pine does not use the "compose=" portion of mailcap entries (and doesn't +# provide a general method of composing different types of messages). +# Pine doesn't pay attention to "copiousoutput", but always pipes the output +# to its standard scrolling text window if "needsterminal" is not set. +# If "needsterminal" is set, then Pine sets the terminal or terminal window +# back to the state it was in when Pine was started and lets the viewer run. +# When the viewer finishes, Pine resets the terminal and redraws the screen. +# If any user interaction with the viewer is required and the viewer runs +# in the same terminal window as Pine, then "needsterminal" should be set. +# The "test=" commands are used as defined in RFC1524, except that the +# data file is not available to the test command. +# +# Since mailcap is only used from the attachment viewer, the message being +# viewed will always be a single part, so "multipart" entries in mailcap have +# no effect on Pine. Type "text/plain" with "charset=usascii" or charset +# matching the character-set variable are intercepted and displayed by Pine +# in the normal way, not displayed by a mailcap viewer. Besides those +# exceptions just listed, all other types and subtypes are subject to +# being displayed by a mailcap viewer. If no match is found for types text +# or message, Pine will display them in its usual way. +# +# As a special case, the "image-viewer" variable from the pinerc file is +# supported as if an extra entry for type image/* came first in the +# personal mailcap file. That's for backwards compatibility. +# +# +# The following line causes the xv program to be used to display all +# image types if the DISPLAY variable is set (indicating the user is +# using X).
