It used to be in csound_new.zip, but now seems not to.

As a text file, in the format: time, value. 
You could have read the file with kread2 opcode if it had still been around
(where did it go?), but that would be kind of silly, since the opcode rms 
can do the same task with no intermediate step.
Of course, for realtime, perhaps kread would have been faster?

Have an old version of envext in my Csound directory, so if you want it 
I could mail it, it's just a few kB.
