When I see "slurp", I know exactly what it does: reads a full fileinto a string. If you don't get the same immediate reaction, you really should: google "file slurp" and see that it's the way this facility is called in many programming languages. Now that "slurp" is taken by an unrelated command, "zslurp" is an obvious alternative
So it is. Not 'zlurp' but 'zslurp' -- that fixes it. Besides, it's your baby and you should make the call.
