#
# == NAME
# kernel.sh - for Frugalware
#
# == SYNOPSIS
# Common schema for kernel packages.
#
# == EXAMPLE
# * To build a vanilla upstream kernel with a custom version and config:
# --------------------------------------------------
# pkgver=2.6.20
# pkgrel=1
# _F_kernel_name="-custom"
# Finclude kernel
# --------------------------------------------------
# * To use a given patchset (for example -ck):
# --------------------------------------------------
# pkgver=2.6.20
# pkgrel=1
# _F_kernel_name="-ck"
# _F_kernel_patches=(http://www.kernel.org/pub/linux/kernel/people/ck/patches/\
# 2.6/2.6.20/2.6.20-ck1/patch-2.6.20-ck1.bz2)
# Finclude kernel
# --------------------------------------------------
# == OPTIONS
# You are strongly recommended to use the pkgver and pkgrel variables, however
# all the variables are optional. Here is a list of them:
#
# * _F_kernel_vmlinuz (defaults to arch/$arch/boot/bzImage): path to the kernel
# binary
# * _F_kernel_name (defaults to ""): include a string in the kernel version
# string (example: "-mygrsec")
# * _F_kernel_ver (defaults to $pkgver): the version of the kernel
# * _F_kernel_rel (defaults to $pkgrel): the release of the kernel (used in the
# kernel version string)
# * _F_kernel_dontfakeversion if set, don't replace the kernel version string
# with a generated one (from _F_kernel_ver, _F_kernel_name and _F_kernel_rel)
# * _F_kernel_uname: specify the kernel version manually (defaults to
# $_F_kernel_name-fw$_F_kernel_rel)
# * _F_kernel_path: vmlinuz on x86
#
# == OVERWRITTEN VARIABLES
# * pkgver (if not set)
# * pkgrel (if not set)
