# This script wraps i3status output and inject mail status, or just reports
# status on command line. It is based on 'wrapper.py' script by Valentin
# Haenel, which could be found at:
# http://code.stapelberg.de/git/i3status/tree/contrib/wrapper.py
#
# To use it, ensure your ~/.i3status.conf contains this line:
# output_format = "i3bar"
# in the 'general' section.
# Then, in your ~/.i3/config, use:
# status_command i3status | path/to/check_mail.py ...
# In the 'bar' section.
#
# Or just run:
# ./check_mail.py -1 ...
#
# Information on command line arguments (flags) may be obtained by running
# ./check_mail.py -h
