'
Show a Gri hint for today, picked at random from hints stored on the web
at

These will be downloaded at most once per day. Since the download might
take a couple of seconds, the hint is only downloaded once per day,
being cached for later uses in the given day, in a user file called
`~/.gri-hint-cache'. This command will
produce warning if the system program `lynx
' is not available for
downloading.
