# shellcheck disable=SC2030,SC2031,SC2059
# The above line must be directly after the shebang line.
# Disables these warnings:
# 2030 - Modification of var is local (to subshell caused by pipeline).
# shell check 0.4.6 gets confused by the read -t 1 command and interprets
# the '1' as $1 getting modified.
# 2031 - var was modified in a subshell. That change might be lost.
# caused by shell check bug with SC2030? This causes any $1 from that
# point on to be flagged.
# 2059 - Don't use variables in the printf format string. Use printf "..%s.." "$foo".
# This is used for all of our color printing.
