-Further, as this code is used to generate both a Nanomsg and NNG based version,
-there are some modules which are specific to the underlying transport being
-used. The original code was based on Nanomsg, thus any changes resulting from
-the port to NNG, are in files with the same name plus _nng (e.g. rtable_static.c
-is the original module, and rrable_nng_static.c is the NNG version).

+Further, as this code is used to generate libraries which make use of different
+transport mechanisms, there are some modules which are specific to the
+underlying transport being used. The original code supported both Nanomsg and
+NNG, however Nanomsg has been phased out (starting with 1.0.45). File naming
+convention for modules which are transport specific originally included a
+suffix (e.g. _nng), however as the directory structure was reorganised, and
+transport specific directories, plus a common directory, have been created,
+the need for the suffix has been eliminated (existing files were not changed).
