# MakeInc.dir contains the recursion rules for the build system.
# For instance, the "build_installhdrs_md" target is auto-generated
# such that make(1) recurses into a specified set of subdirectories
# (building "build_installhdrs_md" in turn at each level) before
# building the special "do_installhdrs_md" target at the current
# level. "do_installhdrs_md" is defined in MakeInc.rule.
#

# $(1) is the name of the target to produce that will perform the
#      recursive behavior via dependencies
# $(2) is a list of subdirectories to recurse into
# $(3) is the target to build with a sub-make after
#      the subdirectories have been recursed into
# $(4) should be "1" if TARGET should be pinned to the per-arch
#      build COMPONENT directory, or empty if it should recurse
#      in lockstep with the source recursion
