+# This Makefile fragment is included by other Makefiles to set all of
+# the variables saved through MAKEVARS.  Typical usage is:
+#
+# .include "../../mk/bsd.makevars.mk"
+# .if !define(EXPENSIVE_VAR)
+# EXPENSIVE_VAR!=      ( ... an expensive computation ... )
+# .endif
+# MAKEVARS+=   EXPENSIVE_VAR
+#
+# This causes EXPENSIVE_VAR to be computed, then subsequently stored in
+# the variable cache file.  The next time through, EXPENSIVE_VAR is
+# set by bsd.makevars.mk, which avoids running the expensive computation
+# again.
+#
+# The cache files are created as we pass through each phase of the build,
+# and we only include the latest cache file that was created.
