Thanks to Philippe Tanguy, here is a French translation of KPL.Core.Libraries.xml.

This XML file contains the definitions of all of the classes and methods and functions and properties which are available in Phrogram.

To us, place it in the folder where your Phrogram executable resides with a separate name - say, KPL.Core.Libraries.French.xml. Then, rename the existing version to something else, like KPL.Core.Libraries.old.xml or KPL.Core.Libraries.English.xml (that way, you will still have it if you ever want to revert back). Then change the name of this new version to KPL.Core.Libraries.xml, and voilà ...

Phrogram's class library browser definitions will now be in French!
