[Geotiff] cylindrical equal-area not supported by GeoTIFF?

[John Maurer]

Dear GeoTIFF list,
I'm getting the following error when trying to create a GeoTIFF using 
geotifcp for data in a cylindrical equal-area projection:

 > geotifcp -g Ml_geo.txt EASE-F13-ML2006166D.19V.tif 
EASE-F13-ML2006166D.19V.geo.tif
Parsing Error at 'CT_CylindricalEqualArea'
Failure in GTIFImport
Exit 255

I have gathered in previous message and online documentation that 
cylindrical equal-area projections aren't supported yet in 
GeoTIFF/libgeotiff: is this true?, and if so, are there things in the 
works to have this added? Thanks for your help! At the bottom of this 
message, I've pasted my GeoTIFF header from the above command 
(Ml_geo.txt) for reference.
Best Regards,
John Maurer
