# Configuration-Variables used by this eclass:
#
# Automatically filled with values:
# (You can change them after inherit if you need to)
#   VDRPLUGIN    - Name of the plugin
#   S            - Path of the sources
#   KEYWORDS     - Set ebuild to state masked
#   SLOT         - Set to 0
#
#
#
# You must set in your ebuild
#   SRC_URI      - Download location
#   HOMEPAGE     - Homepage of plugin
#   DESCRIPTION  - Description
#   LICENSE      - License of plugin (GPL-2)
#   DEPEND       - Dependencies to vdr etc.
#

# This eclass exports these functions:
#    src_unpack
#    src_compile
#    src_install
#    pkg_postinst
#

# If this implementation is good for you,
# you have nothing to do, else you can inherit this
# Version and change it how you like.

# Example for src_unpack:
#
# inherit eutils
# src_unpack() {
#         # inherited version
#         vdrplugin_src_unpack
#
#         # Added code
#         epatch ${FILESDIR}/patch-no5.diff
