# Script to export json data from Trello
# Written by ZPH <zander@civet.ws>

# Caveats:
# -API limits the number certain parameters returned.
#   -JSON output may be truncated for large boards; further research needed.

# Variables to set as Environmental Variables or directly in script

# Board hashes can be found in URL of board or by using script in Trello-Archiver
