 +  * check the modules' documentation that export functions to Lua (they match subpackage name) to understand better the functionality provided by specific functions
 +  * the parameters must be strings if the prototype have them in between double quotes, or integers if there are no double quotes
 +  * any parameter specified in prototype enclosed in between square brackets is optional

 +==== sr.modf ====
 +
 +Run a function exported by a module
