 # vdr-plugin.eclass
 #
 #   eclass to create ebuilds for vdr plugins
 #

 # Example ebuild (basic version without patching):
 #
 #	EAPI="2"
 #	inherit vdr-plugin
 #	IUSE=""
 #	SLOT="0"
 #	DESCRIPTION="vdr Plugin: DVB Frontend Status Monitor (signal strengt/noise)"
 #	HOMEPAGE="http://www.saunalahti.fi/~rahrenbe/vdr/femon/"
 #	SRC_URI="http://www.saunalahti.fi/~rahrenbe/vdr/femon/files/${P}.tgz"
 #	LICENSE="GPL-2"
 #	KEYWORDS="~x86"
 #	DEPEND=">=media-video/vdr-1.6.0"
 #
 #

 # For patching you should modify src_prepare phase:
 #
 #	src_prepare() {
 #		epatch "${FILESDIR}"/${P}-xxx.patch
 #		vdr-plugin_src_prepare
 #	}

 # Installation of a config file for the plugin
 #
 #     If ${VDR_CONFD_FILE} is set install this file
 #     else install ${FILESDIR}/confd if it exists.

 #     Gets installed as /etc/conf.d/vdr.${VDRPLUGIN}.
 #     For the plugin vdr-femon this would be /etc/conf.d/vdr.femon


 # Installation of an rc-addon file for the plugin
 #
 #     If ${VDR_RCADDON_FILE} is set install this file
 #     else install ${FILESDIR}/rc-addon.sh if it exists.
 #
 #     Gets installed under ${VDR_RC_DIR}/plugin-${VDRPLUGIN}.sh
 #     (in example vdr-femon this would be /usr/share/vdr/rcscript/plugin-femon.sh)
 #
 #     This file is sourced by the startscript when plugin is activated in /etc/conf.d/vdr
 #     It could be used for special startup actions for this plugins, or to create the
 #     plugin command line options from a nicer version of a conf.d file.

 # HowTo use own local patches; Example
 #
 #	Add to your /etc/make.conf:
 # 	VDR_LOCAL_PATCHES_DIR="/usr/local/patch"
 #
 #	Add two DIR's in your local patch dir, ${PN}/${PV},
 #	e.g for vdr-burn-0.1.0 should be:
 #	/usr/local/patch/vdr-burn/0.1.0/
 #
 #	all patches which ending on diff or patch in this DIR will automatically applied
 #
