# You can use this script in two ways
#   1. Source it in to an existing script to get access to your credentials
#      e.g.
#      #!/bin/bash
#      . ~/bin/op-wrapper
#      details=$(op get item 'Top Secret Password')
#   2. Wrap another script or command with this script
#      e.g.
#      ~/bin/op-wrapper ./myscript up down left right
