And the only reason I have a monthly update is that setting it up that
way was the 'least often' I could get it without complicating the
shell command line too much. (I wanted to keep it all in the crontab,
which has a line-length limitation I haven't bothered to look into
much. But after a certain number of characters, it simply cuts the
rest then passes the result to the shell.)
