#  Define a little function to draw a progress indicator... Jaws!
#  i forever increments; when 1 mod 60 = 0, we start decrementing $pos or
#  incrementing it, depending on current direction of travel. Requires that
#  the function is called as a background process before some task is performed, 
#  then killed when complete, which requires that you know the process spawned by the
#  background call to the function. For example:
# 
#  jaws &
#  jawsp=$!
#  apt-get install some_program
#  kill $jawsp 
#  wait $jawsp 2>/dev/null
