## debug ?-option value? ?-option value?...
## A command to make debugging more convenient. Print strings, arrays
## and the values of variables as specified by the arguments.
##
## Also allows the setting of an array called debug which will pick up
## options for all debug commands.
##
## We create this command in the ::request namespace because we want the
## user to be able to use the debug array without actually having to set
## it at the global level.
##
## Options:
##
## -subst <on|off> - Each word should be considered a variable and subst'd.
## -separator <string> - A text string that goes between each variable.
## -ip <ip address> - A list of IP addresses to display to.
