+# 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
