# Kernel-dependent paths.
#
# Some deliverables may depends on linux kernel.
#
# For make "one user installation for several kernels" paradigm works,
# installation directory for that deliverables should include
# kernel-version part(like "3.10.2-generic").
#
# So, components installed by user installation can determine at runtime,
# which kernel-dependent deliverable should be used on currently loaded system.
# They do selection using 'uname -r' request.
#
# For define variables represented kernel-dependent directories,
# we use strings containing "%kernel%" stem.
# kernel_path(kernel_version RESULT_VARIABLE pattern ...)
#
# Form concrete path representation from kernel-dependent pattern(s).
# Replace occurence of %kernel% in pattern(s) with given @kernel_version string.
# Result is stored in the RESULT_VARIABLE.
#
# @kernel_version may be concrete version of the kernel,
# or variable reference in some language.
