+#
+# Non-recursive targets are attached to existing make targets. The

+# each target in this list, the NONRECURSIVE_TARGET_<target> variable will
+# contain a list of partial variable names. We will then look in variables
+# named NONRECURSIVE_TARGETS_<target>_<fragment>_* for information describing
+# how to evaluate non-recursive make targets.

+# Targets are defined by the following variables:
+#
+#   FILE - The make file to evaluate. This is equivalent to
+#      |make -f <FILE>|
+#   DIRECTORY - The directory whose Makefile to evaluate. This is
+#      equivalent to |make -C <DIRECTORY>|.
+#   TARGETS - Targets to evaluate in that make file.
+#
+# Only 1 of FILE or DIRECTORY may be defined.
+#
+# For example:
+#
+# NONRECURSIVE_TARGETS = export libs
+# NONRECURSIVE_TARGETS_export = headers
+# NONRECURSIVE_TARGETS_export_headers_FILE = /path/to/exports.mk
