# Example: /etc/init.d/drizzle drizzle_get_param pid-file

# drizzle_status() checks if there is a server running and if it is accessible.
# "check_alive" insists on a pingable server, "check_dead" also fails
# if there is a lost drizzled in the process list
# Usage: boolean drizzle_status [check_alive|check_dead] [warn|nowarn]
