Your design looks fine. I prefer the library approach which means you  
would "start using" the s_lib_functions.rev stack so it is available  
to all scripts. Libraries usually make the most sense for general  
handlers you want to be globally available.

You could make s_lib_functions.rev a substack of s_main.rev. If you  
have more than one library stack you could also create a  
"libraries.rev" stack on disk and make s_lib_functions a substack of  
the library stack. In the end you would get the same result though.
