-# This eclass provides functions for querying the installed kernel
-# source version, selected kernel options etc.
+# Description: This eclass is used as a central eclass for accessing kernel
+# related information for sources already installed.
+# It is vital for linux-mod to function correctly, and is split
+# out so that any ebuild behaviour "templates" are abstracted out
+# using additional eclasses.

+
+# A Couple of env vars are available to effect usage of this eclass
+# These are as follows:
+#
+# Env Var Option Description
+# KERNEL_DIR <string> The directory containing kernel the target kernel
+# sources.
+# CONFIG_CHECK <string> a list of .config options to check for before
+# proceeding with the install. ie: CONFIG_CHECK="MTRR"
+# You can also check that an option doesn't exist by
+# prepending it with an exclamation mark (!).
+# ie: CONFIG_CHECK="!MTRR"
+# <CFG>_ERROR <string> The error message to display when the above check
+# fails. <CFG> should reference the appropriate option
+# as above. ie: MTRR_ERROR="MTRR exists in the .config
+# but shouldn't!!"
+# KBUILD_OUTPUT <string> This is passed on commandline, or can be set from
+# the kernel makefile. This contains the directory
+# which is to be used as the kernel object directory.
+
+# There are also a couple of variables which are set by this, and shouldn't be
+# set by hand. These are as follows:
+#
+# Env Var Option Description
+# KV_FULL <string> The full kernel version. ie: 2.6.9-gentoo-johnm-r1
+# KV_MAJOR <integer> The kernel major version. ie: 2
+# KV_MINOR <integer> The kernel minor version. ie: 6
+# KV_PATCH <integer> The kernel patch version. ie: 9
+# KV_EXTRA <string> The kernel EXTRAVERSION. ie: -gentoo
+# KV_LOCAL <string> The kernel LOCALVERSION concatenation. ie: -johnm
+# KV_DIR <string> The kernel source directory, will be null if
+# KERNEL_DIR is invalid.
+# KV_OUT_DIR <string> The kernel object directory. will be KV_DIR unless
+# koutput is used. This should be used for referencing
+# .config.

+# A Couple of env vars are available to effect usage of this eclass
+# These are as follows:
+#
+# Env Var Option Default Description
+# KERNEL_DIR <string> /usr/src/linux The directory containing kernel
+# the target kernel sources.
+# BUILD_PARAMS <string> The parameters to pass to make.
+# BUILD_TARGETS <string> clean modules The build targets to pass to make.
+# MODULE_NAMES <string> This is the modules which are
+# to be built automatically using the
+# default pkg_compile/install. They
+# are explained properly below.
+
+
+# MODULE_NAMES - Detailed Overview
+#
+# The structure of each MODULE_NAMES entry is as follows:
+# modulename(libmodulesdir:modulesourcedir)
+# for example:
+# MODULE_NAMES="module_pci(pci:${S}/pci) module_usb(usb:${S}/usb)"
+#
+# what this would do is
+# cd ${S}/pci
+# make ${BUILD_PARAMS} ${BUILD_TARGETS}
+# insinto /lib/modules/${KV_FULL}/pci
+# doins module_pci.${KV_OBJ}
+#
+# cd ${S}/usb
+# make ${BUILD_PARAMS} ${BUILD_TARGETS}
+# insinto /lib/modules/${KV_FULL}/usb
+# doins module_usb.${KV_OBJ}
+#
+# if the modulessourcedir isnt specified, it assumes ${S}
+# if the libmodulesdir isnt specified, it assumes misc.
+# if no seperator is defined ":" then it assumes the argument is modulesourcedir
