+# 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).
