There are no documentation on CEF. The origin of the format in FreeType
dates to the first version of the Adobe SVG Plugin, which pulled files
with names like "helvetica.cef" from Adobe's Demo SVG pages.

A quick view in a hex editor showed that these were simply OpenType/CFF
fonts without the few mandatory tables like "head", etc.. which is why
adding support for them in FT2 was trivial. I needed that to test the
SVG rendering library I was developping at the time.

I don't know if CEF is still in use, but the format is pretty easy
to generate. Make an OTF/CFF font and strip some of its SFNT tables.

Hope this helps,
