# spinner.sh
#
# Display an awesome 'spinner' while running your long shell commands
#
# Do *NOT* call _spinner function directly.
# Use {start,stop}_spinner wrapper functions

# usage:
#   1. source this script in your's
#   2. start the spinner:
#       start_spinner [display-message-here]
#   3. run your command
#   4. stop the spinner:
#       stop_spinner [your command's exit status]
#
# Also see: test.sh
