%% File : rpp_srmain.tlc
%% Abstract:
%% This file generates the "main" file for the RPP target on top of the RPP
%% library and the FreeRTOS operating system.
%%
+%% The sr prefix is standard to mark Single Tasking main, which is the case. See
+%% rpp_file_process.m description above for more information about this.
