# Check that crond is running.  Returns ZERO if cron daemon is running.
# Returns nonzero if cron daemon is NOT running and prints a warning.  
#
# The -v flag forces a message giving you the crond status in any case.
#
# It makes no sense to run this from cron!  Instead, put it in 
# precmd or periodic in your .tcshrc or in PROMP_COMMAND in your .bashrc
