 # @DESCRIPTION:
 # Eclass for easing maitenance of vdr plugin ebuilds

 # Plugin config file installation:
 #
 # A plugin config file can be specified through the $VDR_CONFD_FILE variable, it
 # defaults to ${FILESDIR}/confd. Each config file will be installed as e.g.
 # ${D}/etc/conf.d/vdr.${VDRPLUGIN}

 # Installation of rc-addon files:
 # NOTE: rc-addon files must be valid shell scripts!
 #
 # Installing rc-addon files is basically the same as for plugin config files
 # (see above), it's just using the $VDR_RCADDON_FILE variable instead.
 # The default value when $VDR_RCADDON_FILE is undefined is:
 # ${FILESDIR}/rc-addon.sh and will be installed as
 # ${VDR_RC_DIR}/plugin-${VDRPLUGIN}.sh
 #
 # The rc-addon files will be sourced by the startscript when the specific plugin
 # has been enabled.
 # rc-addon files may be used to prepare everything that is necessary for the
 # plugin start/stop, like passing extra command line options and so on.

 # Applying your own local/user patches:
 # This is done by using the epatch_user() function of the eutils.eclass.
 # Simply put your patches into one of these directories:
 # /etc/portage/patches/<CATEGORY>/<PF|P|PN>/
 # Quote: where the first of these three directories to exist will be the one to
 # use, ignoring any more general directories which might exist as well.
 #
 # For more details about it please take a look at the eutils.class.
