Documentation:
Specify an alist for PostScript utility processing (PS utility database).

The alist element has the form:

(SYMBOL UTILITY MUST-SWITCHES PAPERSIZE N-UP LANDSCAPE DUPLEX TUMBLE OUTPUT
SWITCHES DEFAULT...)

Where:

SYMBOL It's a symbol to identify a PostScript utility. It's for
`pr-ps-utility' variable setting and for menu selection.
Examples:
'mpage
'psnup

UTILITY Name of utility for processing a PostScript file.
See also `pr-path-alist'.
Examples:
. for GNU or Unix system:
"mpage"
"psnup -q"

. for Windows system:
"c:/psutils/psnup -q"

MUST-SWITCHES List of sexp's to pass as options to the PostScript utility
program. These options are necessary to process the utility
program and must be placed before any other switches.
Example:
. for psnup:
'("-q")

PAPERSIZE It's a format string to specify paper size switch.
Example:
. for mpage
"-b%s"

N-UP It's a format string to specify n-up switch.
Example:
. for psnup
"-%d"

LANDSCAPE It's a string to specify landscape switch. If the utility
doesn't have landscape switch, set to nil.
Example:
. for psnup
"-l"

DUPLEX It's a string to specify duplex switch. If the utility doesn't
have duplex switch, set to nil.
Example:
. for psnup
nil

TUMBLE It's a string to specify tumble switch. If the utility doesn't
have tumble switch, set to nil.
Example:
. for psnup
nil

OUTPUT It's a string to specify how to generate an output file. Some
utilities accept an output file option, but some others need
output redirection or some other way to specify an output file.
Example:
. for psnup
" " ; psnup ... input output

. for mpage
">" ; mpage ... input > output

SWITCHES List of sexp's to pass as extra options to the PostScript utility
program.
Example:
. for psnup
'("-q")
nil

DEFAULT It's a way to set default values when this entry is selected.
It's a cons like:

(VARIABLE . VALUE)

Which associates VARIABLE with VALUE. When this entry is
selected, it's executed the following command:

(set VARIABLE (eval VALUE))

Note that VALUE can be any valid lisp expression. So, don't
forget to quote symbols and constant lists.
If VARIABLE is the special keyword `inherits-from:', VALUE must
be a symbol name setting defined in `pr-setting-database' from
which the current setting inherits the context. Take care with
circular inheritance.
Examples:
'(pr-file-landscape . nil)
'(pr-file-duplex . t)
'(pr-gs-device . (my-gs-device t))

This variable should be modified by customization engine. If this variable is
modified by other means (for example, a lisp function), use `pr-update-menus'
function (see it for documentation) to update PostScript utility menu.

NOTE: Don't forget to download and install the utilities declared on
`pr-ps-utility-alist'.

Examples:

* On GNU or Unix system:

'((mpage "mpage" nil "-b%s" "-%d" "-l" "-t" "-T" ">" nil)
(psnup "psnup" ("-q") "-P%s" "-%d" "-l" nil nil " " nil
(pr-file-duplex . nil) (pr-file-tumble . nil))
)

* On Windows system:

'((psnup "c:/psutils/psnup" ("-q") "-P%s" "-%d" "-l" nil nil " "
nil (pr-file-duplex . nil) (pr-file-tumble . nil))
)
