+Builds into object files into a temporary ~nim-cache~ directory generated by
+rmsbolt, which will then be copied and dissassembled.
+C++ backend is also possible to either with ~nim cpp~ or ~nim c
+--passC:-std=gnu++14~ and uses ~c++filt~ demangler.

+Use the ~{.exportc.}~ pragma for at least the main procedure that will be 
dissassembled.

 * Integrations
 This section covers integrations that RMSbolt provides, which make it easier to
 use RMSbolt with complex projects with many dependencies.
