# How to run nxtvepg in daemon mode
# =================================
# 
# (1) Setup nxtvepg using the GUI:  Just start nxtvepg, specify the
#     device, let it scan for EPG providers, configure everything
#     the way you like it.
# (2) Copy the resulting config file $HOME/.nxtvepgrc to
#     /etc/nxtvepgrc
# (3) "rcnxtvepg start" (as root) will start nxtvepg in daemon mode.
# (4) "insserv nxtvepg" (as root) will enable the start script, so
#     nxtvepg will be started every time you boot the system.

# Description:       Starts nxtvepg in daemon mode.
