 actually want to modify a setting from the OS-specific file, there is nothing
 to stop you overriding it in your Local/Makefile.
 
+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
+query the --cflags and --libs for the given name, when building anything
+dependent upon the component associated with the `_PC' variable.  For lookups,

+corresponding _INCLUDE and _LIBS options, which will be ignored.  If the lookup
