# @BLURB: common vdr plugin ebuild functions
# @DESCRIPTION:
# Eclass for easing maintenance of vdr plugin ebuilds

# @ECLASS-VARIABLE: VDRPLUGIN
# @OUTPUT_VARIABLE
# @DESCRIPTION:
# The name of the vdr plugin, plain name without "vdr-" or "plugin" prefix or suffix.
# This variable is derived from ${PN} and is read-only for the ebuild.

# @ECLASS-VARIABLE: VDR_CONFD_FILE
# @DEFAULT_UNSET
# @DESCRIPTION:
# 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}

# @ECLASS-VARIABLE: VDR_RCADDON_FILE
# @DEFAULT_UNSET
# @DESCRIPTION:
# 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.
#
# NOTE: rc-addon files must be valid shell scripts!

# @ECLASS-VARIABLE: GENTOO_VDR_CONDITIONAL
# @DEFAULT_UNSET
# @DESCRIPTION:
# This is a hack for ebuilds like vdr-xineliboutput that want to
# conditionally install a vdr-plugin

# @ECLASS-VARIABLE: PO_SUBDIR
# @DEFAULT_UNSET
# @DESCRIPTION:
# By default, translation are found in"${S}"/po but this
# default can be overridden by defining PO_SUBDIR.
#
# Example:
# @CODE
# PO_SUBDIR="bla foo/bla"
# @CODE

# Applying your own local/user patches:
# This is done by using the
# (EAPI = 5) epatch_user() function of the eutils.eclass,
# (EAPI = 6,7) eapply_user function integrated in EAPI = 6.
# Simply add 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.
