# Jeremy Huddleston <eradicator@gentoo.org>
#
# Usage:
# The main purpose of this eclass is to simplify installing xmms plugins
# which for the various players that support the xmms API (mainly xmms and
# bmp, but this can be expanded to noxmms as well).
#
# The package is assumed to work by default with xmms.  If it will not work
# with BMP, then set NOBMP=1 in the ebuild.
#
# Source Code:
# You have multiple methods with which to specify how we get the source code
# for the patckages.
#
# (1) - Separate tarballs
# If your package provides separate tarballs for the xmms and bmp plugins,
# then specify them in the XMMS_SRC_URI and BMP_SRC_URI variables.
# XMMS_SRC_URI="xmms-plugin.tar.bz2"
# BMP_SRC_URI="bmp-plugin.tar.bz2"
# BASE_SRC_URI="common-stuff.tar.bz2"
#
# (2) - xmms->bmp patch
# If you have a patch to turn an xmms plugin into a bmp plugin, specify it
# in the variable XMMS2BMP_PATCH:
# XMMS2BMP_PATCH="${FILESDIR}/${P}-xmms2bmp.patch"
#
# (3) - automated
# The eclass will try to do some sedage to get the plugin to work with bmp.
#
# Common patches:
# If you have patches that need to apply to both xmms and bmp sources,
# Place them in the PATCHES variable:
# PATCHES="${FILESDIR}/${P}-gcc34.patch ${FILESDIR}/${P}-config.patch"
#
# Source Location:
# By default, we assume a ${S} of ${XMMS_S} or ${BMP_S} for the two packages.
# These default to ${XMMS_WORKDIR}/${P} or ${BMP_WORKDIR}/${P}.
# ${XMMS_WORKDIR} and ${BMP_WORKDIR}/${P} default to ${WORKDIR}/xmms and
# ${WORKDIR}/bmp.  You may override ${*_S}, but not the ${*_WORKDIR}.
#
# Documentation:
# Set the DOCS variable to contain the documentation to be dodocd:
# DOCS="ChangeLog AUTHORS README"
#
# Install:
# Set the XMMS_PLUGIN_INSTALL variable to control how src_install works
# 'einstall' - use 'einstall' to install
# 'destdir'  - use 'make DESTDIR="${D}" install || die' to install
# 'doexe' - use 'doexe' to install
# destdir is default
#
# The 'myins_xmms' and 'myins_bmp' variables are used to add extra arguments
# to the install line.  They are optional for einstall and destdir, but they're
# required for doexe.  For doexe, you need to specify the plugin type in the
# 'xmms_plugin_type' variable' and the location of the plugin in the 'myins_*'
# variable.
