# Invoke whatever HTML viewer is installed...
# Usage:
#	htmlview [URL]
#
# Changes:
# v2.0.0
# ------
# - Allow users to override default settings in
#   ~/.htmlviewrc and /etc/htmlview.conf.
#   Users can define X11BROWSER, TEXTBROWSER and
#   CONSOLE variables to indicate their preferences.
# - --remote and --local are deprecated, we don't
#   have any non-browser HTML viewers these days.
