# WARNING: Deprecated Script
# This script will be replaced in the future when something better is implemented.
#
# v4.0.0
# ------
# If DISPLAY is set and gnome-open exists, mimic gnome-open behavior to launch 
# preferred browser.  Due to MIME associations, gnome-open cannot be directly 
# called to view files from htmlview because it will go into an infinite loop.
# text/html associated with htmlview runs mimic_gnome_open, which Just Works.
# (Otherwise fallback to old htmlview behavior.)
#
#   ~/.htmlviewrc and /etc/htmlview.conf.
#   Users may define the TEXTBROWSER variable to
#   indicate their preference for old htmlview.
#
#   /usr/bin/gnome-default-applications-properties
#   Please use the Preferred Application chooser
#   for all other configuration options.
