28 # Installation of a config file for the plugin
29 #
30 # If ${VDR_CONFD_FILE} is set install this file
31 # else install ${FILESDIR}/confd if it exists.
32
33 # Gets installed as /etc/conf.d/vdr.${VDRPLUGIN}.
34 # For the plugin vdr-femon this would be /etc/conf.d/vdr.femon
35
36
37 # Installation of an rc-addon file for the plugin
38 #
39 # If ${VDR_RCADDON_FILE} is set install this file
40 # else install ${FILESDIR}/rc-addon.sh if it exists.
41 #
42 # Gets installed under ${VDR_RC_DIR}/plugin-${VDRPLUGIN}.sh
43 # (in example vdr-femon this would be /usr/share/vdr/rcscript/plugin-femon.sh)
44 #
45 # This file is sourced by the startscript when plugin is activated in /etc/conf.d/vdr
46 # It could be used for special startup actions for this plugins, or to create the
47 # plugin command line options from a nicer version of a conf.d file.
48
49 # HowTo use own local patches; Example
50 #
51 # Add to your /etc/make.conf:
52 # VDR_LOCAL_PATCHES_DIR="/usr/local/patch"
53 #
54 # Add two DIR's in your local patch dir, ${PN}/${PV},
55 # e.g for vdr-burn-0.1.0 should be:
56 # /usr/local/patch/vdr-burn/0.1.0/
57 #
58 # all patches which ending on diff or patch in this DIR will automatically applied
59 #
