# pcmcia.eclass - This eclass facilities writing ebuilds for driver packages
# that may need to build against the pcmcia-cs drivers, depending on kernel
# support, pcmcia-cs version installed, etc.
# It also ensures that any fixes need for pcmcia-cs configuration, driver
# compilation, etc can be located in one spot and be consistent among all
# driver packages
# Author - Peter Johanson <latexer@gentoo.org>
# Variables - You may safely use PCMCIA_SOURCE_DIR and PCMCIA_VERSION in ebuilds
# if this information is needed. These will be blank if kernel PCMCIA support
# is detected.
# Functions - pcmcia_src_unpack unpacks and patches as needed the pcmcia-cs
# sources in ${WORKDIR}/${PCMCIA_SOURCE_DIR} and set the two variables.
# pcmcia_configure will configure the pcmcia-cs sources if that is needed
inherit eutils
