#
# create-directory
#
# Create the directory with the name of the $(@) variable.
#
define create-directory
$(call nl-create-dir,$(@))
endef # create-directory

#
# create-link
#
# Create the symbolic link with the source of the $(<) variable and
# the destination of the $(@) variable.
#
define create-link
$(call nl-create-link)
endef # create-link

#
# check-file <macro suffix>
#
# Check whether a file, referenced by the $(@) variable, should be
# updated / regenerated based on its dependencies, referenced by the
# $(<) variable by running the make macro check-file-<macro suffix>.
#
# The $(<) is passed as the first argument if the macro wants to process
# it and the prospective new output file, which the macro MUST
# generate, as the second.
#
# This macro will ensure that any required parent directories are created
# prior to invoking check-file-<macro suffix>.
#
# This macro is similar to and inspired by that from Linux Kbuild and
# elsewhere.
#
#   <macro suffix> - The name, suffixed to "check-file-", which indicates
#                    the make macro to invoke.
