# - can also use Net::HTTP to do this, which is good for
#   large downloads and uploads of big data
# - the nil assignment makes sure the vars will not
#   have leftovers from previously running this line in irb
#   (e.g. if failure, repIO can have non-nil from -previous-
#   successful call you made earlier in irb).

# a message to stderr if repIO is nil. For JSON [i.e. most]
# representations, you will want to examine/print:
#
if(repIO.nil?)
