I am trying to run a script that prompts the user for a desired directory and file name for export. Ideally, this script would be run from the File -> Export menu and pop up a file browser window similar to how the included export scripts function.

The only way I've found to call Blender's file browser is via a file path property for a UI panel (i.e. How to add a "select path" input in a UI addon script?). Is what I'm trying for possible?
