# This is a sample mailcap file based on the sample mailcap file
# contained in the metamail distribution (version 2.7) from Bellcore.
# This sample is for a Unix system.  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.

# 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).  (xv is written by John Bradley, bradley@cis.upenn.edu.  There
# are also other X image viewer programs you could use, such as xloadimage.)

# The effect of the following is to send ALL audio subtypes to the 
# showaudio program.  If possible, it would be desirable to also include
# a test command that could decide whether or not the user could play audio.
# That would be something like "test=can_do_audio %t".  (Showaudio is a shell
# script included in the metamail distribution.)
