+contained in email messages.  It parses an email message or file and scans it
+for URLs and email addresses.  It then displays the URLs and their context
+within the message, and allows you to choose one or more URLs to send to your
+Web browser.  Alternatively, it send a list of all URLs to stdout.  It is a
+replacement for the @code{urlview} program.")
