# Title: Start Import Job for PhotoPrism from CLI
# Purpose: with a single shell script, kick off an import process for a named import directory in PhotoPrism
# History:
# Usage:
#    You can dot-source this script to get the functions.
#    You can also just call the script by itself, with an optional env var CONFFILE.
#    Conffile must contain dot-source script that contains variables: username password url directory
# Dependencies:
#    CONFFILE
#    req-devuan: jq
# References:
#    LW devtools
