-there are some modules which are specific to the underlying transport being

External Names
All externally facing function names and constants will start with rmr_ or
-RMR_ repsectively (RIC Message Router). For the time being, there is a

set of mappings from the old uta_* names to rmr_* names. The user code must
define UTA_COMPAT to have these ensbled.
Internal Names

Requirements
-To build the RMR libraries, both Nanomsg and NNG must be installed, and if not
-installed in the standard places (e.g. /usr/local/include and /usr/local/lib),
-then the proper references must be made in C_INCLUDE_PATH, and LD_LIBRARY_PATH.
+To build the RMR libraries, NNG must be installed, or the external references
+in the source tree must be used to pull and build the NNG library. It might
+be necessary to alter the values of C_INCLUDE_PATH, LD_LIBRARY_PATH, or
+LIBRARY_PATH to reflect the instalation location when the installed version
+ot NNG is being used.
To install see the instructions on their html sites:
https://github.com/nanomsg/nng
- https://nanomsg.org/download.html
+The default CMake build will not require NNG to be installed, and this is the
+easiest way to build.
