Where is forms.php?

[SSAgov]

In the 6.1.0 Developer Guide it states that:

forms.php: This file contains two functions to render specific JavaScript for validation or other actions you might want to perform during edits/saves. By default you can leave these empty and have them return „‟;

I implies it should be in each module: <module>/metadata , but I only see it in a few, none of which I need (ie- Opportunties)



Thanks!
