[gradsusr] is "read" deprecated?

[Rick Danielson]

      There remains a reference to "read" at

http://cola.gmu.edu/grads/gadoc/script.html#intrinsic

but as of grads-2.0.2 and above, this intrinsic function
appears to be unrecognized.  Having the option to read
some simple ASCII data and add a few extra marks on
a graphic seems worthwhile.  Is it now only an option
to do so via, say, pygrads?
