# This little perl script is a simple filter for text/x-vcard
# attachments. I'm pretty sure I've *not* included everything
# possible in here, but it "works for me". Feel free to improve
# in any way you see fit.
#
# Here is how I use it. In my ~/.mutt_mailcap (use your filename of
# choice) I have the following entry:
#
# text/x-vcard; mutt.vcard.filter; copiousoutput
#
# All you then need to do is add a line like:
#
# auto_view text/x-vcard
#
# to your ~/.muttrc (use your filename of choice).
#
