La cage aux folles - how can I get the original french movie script?

Movie scripts in any language exist in several different versions:

• spec script -- as originally sold
• adapted script -- from another medium
• shooting script -- used during production
• transcript script -- dialog keyed from completed film.

This film is credited as being written by:

• Francis Veber
• Edouard Molinaro
• Marcello Danon
• Jean Poiret

...based on the play by Jean Poiret.

There don't seem to be any commercially available copies of the script. However, you can review the online script sources (link below) to attempt to locate the script you want.
