NX Where is the syntax for Ribbon Toolbar files and other menu related files explained?

What is the format / syntax used for the Ribbon toolbar files and other menu 
related configuration files? 
Which files should be modified to create customized ribbon toolbar interface?

Solution

The documentation contains full details of this, however it can be difficult
to find as it is not referenced directly within the main help menu.
It is found in the Programming Tools Section:




Then under the section "Menuscript User's Guide".



Within the guide are many examples of how the menu files can be modified and the syntax that should be used.
