urlview is a curses program for extracting URLs from text files and displaying a menu from which you can select a specific URL to view using your favorite browser program. It was originally part of mutt. See /etc/urlview.conf on how to configure mutt, tin, or your default browser. Please be aware that /etc/urlview.conf and /usr/bin/url_handler.sh are configuration files, so they are not overwritten on upgrades. Be sure to merge/move the .new files after each upgrade.
