# a bash shell wrapper around use of /usr/local/games/astrolog/astrolog
# Invocation with no arguments:
# generate current calendar report for website
# generate current time-space file for astrolog
# (used also by manual invocations for astrolog)
# generate current astrolog chart for website
# generate current astrolog report for website
# generate current weather report for website
# this should be invoked every 15 minutes by cron;
# (if you change the period here, change also the refresh line for the generated html):
# 09,24,39,54 * * * * /usr/local/bin/astrolog 2>> $HOME/.chronicle.log 1>&2
# Optional Arguments specify the date and time of the astrolog chart to be generated (then quit),
# optionally followed by the event name, e.g. Full_Moon, (no spaces) (default="Today"):
# astrolog 2017 Aug 21 06:17 Full_Moon
# Optional Arguments are "-d" and the date+time arguments, to delete a previously generated astrolog, and quit.
# astrolog -d 2017 Aug 21 06:17
# Optional Argument is "-g" to generate an image gallery for the astrolog directory and quit.
# Optional Argument is "-m" to generate charts for all {Full,New} Moons this calendar year and quit.

# /imgs/clipart/portrait/astrolog.png is not yet referenced, it would be good to add it to today.html!
