Notes:

• You need to compile the document using XeLaTeX as this class uses the Delta Jaeger font family as recommended by ETS' "Image de marque ÉTS" document, Section Applications, page 2.
• The logos are PDF versions of the PS files available at ETS' website.
• This class uses the eforms package to create the signature field. The package is part of the "The AcroTeX education bundle" and is included here in the ./acrotex directory as it is a Contrib in TexLive.
