+Mailcap files, defined in [RFC 1524][rfc1524], allow you to tell you
+mail clients, web browsers, and other programs how you want to view
+and edit various MIME types.  Since interaction with your mailcap
+files often occurs deep within the bowels of your program, I've
+written up a very simple [[Python]] script to test your mailcap
+entries: [[mailcap-test.py]].  Enjoy!
