How to submit a script module request with proto
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

When a feature request for supporting a scripting language or interpreter lib
is filed, the process can be speeded up big times if a prototype is submitted.
The prototype is a standalone, minimalistic C application, typically in a
single main.c spanning about 100 lines, accompanied with a script
fewliner written in the given scripting language.

The prototype serves two purposes:
 - it demonstrates that the lib meets the requirements (see script_reqs.txt)
 - code sections will be copied into the module code

What the C program must have:

1. a main(); doesn't need to process CLI args
2. init the lib, if required
3. create a script context; creating multiple contexts is not required, but
   it must be clear from the code how to do it
4. load the example script into the context (step 3. and 4. may be merged)
5. code that calls a script function using an array as list of arguments
   (to demonstrate how to call a script function with variable number of arguments)
6. code that registers a C function in the script context, using two different
   function names
7. a C function, registered in point 6 that finds out the name of the function
   being called; print the name to stdout
8. the C function of point 7. should convert all arguments received from the
   script to string and print them to stdout
9. the C function should demonstrate how to return a string
10. if the lib supports RunData, code that feeds the script with data
11. code that destroys the script context
12. code that uninitializes the library, if applicable
