# This is the script formerly known as loadDB2, and then known as NPL-update.

# It is used to update
# the database when it comes to the WeBWorK Open Problem Library (OPL).
# This should be run after doing a git clone or pull for the OPL
# files.

# In order for this script to work:
#   1) The OPL downloaded to your machine (the .pg files)
#   2) Configuration for the OPL in site.conf needs to be
#      done (basically just setting the path to the OPL files).
