+When building Exim with dynamically loaded lookup support, for "LOOKUP_FOO",
+you can define "LOOKUP_FOO_INCLUDE" and "LOOKUP_FOO_LIBS", for includes and
+libraries specific only to that module.  These rules are only used where the
+relevant lookup is a module.  These options are not explicitly listed below.

+Variables with names endined `_PC' are used for pkg-config integration; setting
+the value to the name of a pkg-config package will cause Exim's build system to
