# This is foomatic-configure, a program to establish and configure
# print queues, drivers, spoolers, etc using the foomatic database and
# companion filters.

# It also comprises half of a programmatic API for user tools: you can
# learn and control everything about the static properties of print
# queues here. With the sister program foomatic-printjob, you can do
# everything related to print queue dynamic state: submit jobs, and
# query, cancel, reorder, and redirect them.

# Connect syntax:
#
# This differs a tad from CUPS's, partly because everything is
# supposed to be a file, and CUPS doesn't entirely reflect that.
# But I'm not really very particular...
#
# If a certain URI is not supported by all the spoolers, the spoolers
# which support it are listed in parantheses, "direct" means direct, 
# spooler-less printing.

-n queuename    Configure/create/delete/query this print queue
 -N Name/Descr.  Long name/Short Description. An empty string ("") deletes
                 the description.
 -L Location     Short phrase describing this printer's location. An empty
                 string ("") deletes the location.
 -c connection   Printer is connected thusly (ex file:/dev/lp0), must
                 be given when a new queue is created
 --ppd ppdfile   Set up the queue using the PPD file ppdfile (can be a
                 manufacturer-supplied PPD file for a PostScript printer).
                 gzip-compressed PPD files are allowed, they must have the
                 extension ".gz".
 -d driver       Foomatic database name for desired printer driver or "raw"
                 for a raw queue. When a non-raw queue is created, the
                 printer must be specified in addition ("-p" option)
 -p printer      Foomatic id for printer. When a non-raw queue is created,
                 the driver must be specified in addition ("-d" option)
 -s spooler      Explicit spooler type (cups, lpd, lprng, pdq, ppr, direct)
 -o option=value Use value as the default for option in this queue
 -o option       Set the switch option by default in this queue
 --backend-dont-disable=value  1: Do not disable CUPS queue when backend
                 fails, 0: Original CUPS behaviour, queue gets disabled
                 when backend fails. Default: 0 (CUPS only)
 --backend-attempts=value  Try that often when backend fails, for infinite
                 retries set the value to zero, for standard CUPS
                 behaviour to 1. Default: 1 (CUPS only)
 --backend-delay=value  Delay in seconds between retries of failed backend.
                 Default: 30 (CUPS only)
 -C [sourcespooler] sourcequeue  Create a copy of a queue. All 
                 characteristics including default option settings are 
                 overtaken. Additional arguments modify the copy. This
                 facility allows to overtake one's configured queues when
                 one changes the spooler.
 -D              Set this queue as the queue used by default.
 -R              Remove this whole queue entirely (just give -n queuename)
 -Q              Query existing configuration (gives XML summary). Supplying
                 no queue name gives info about all installed queues for the
                 current/selected spooler, including the default queue.
 -r              list also remote queues (CUPS only).
 -P              Query existing configuration (gives Perl data structure of
                 the complete information about the queue, including
                 options, possible choices, default settings, ..., for use 
                 by frontends, the output is done as a Perl array, one
                 element per queue), With printer ID and driver name instead
                 of queue name supplied the Perl data structure of the 
                 appropriate printer/driver combo is generated, supplied
                 options are entered as default settings then, from a
                 supplied queue the option default settings are used.
                 Supplying no queue, printer, and driver gives info about
                 all installed queues for the current/selected spooler.
 N               The first index of the Perl array, default: 0
 -O              Print XML Overview of all known printer/drivers
 -X              Print XML data for -p printer and/or -d driver object
 -f              Force rebuild of PPD file from database
 -w              Generate PPD which is compatible to the CUPS PostScript
                 driver for Windows (GUI strings are limited to 39 characters).
                 This applies only to PPDs built from the Foomatic database, it
                 has no influence on PPDs supplied with the "--ppd" option.
 -q              Run quietly and non-interactive
 -h  --help      Show this help message
