-;;
-;; About ps-print
-;; --------------
-;;
-;; This package provides printing of Emacs buffers on PostScript
-;; printers; the buffer's bold and italic text attributes are
-;; preserved in the printer output.  Ps-print is intended for use with
-;; Emacs 19 or Lucid Emacs, together with a fontifying package such as
-;; font-lock or hilit.
-;;
-;;
-;; Using ps-print
-;; --------------
-;;
-;; The Commands
-;;
-;; Ps-print provides eight commands for generating PostScript images
-;; of Emacs buffers:
-;;
-;;        ps-print-buffer
-;;        ps-print-buffer-with-faces
-;;        ps-print-region
-;;        ps-print-region-with-faces
-;;        ps-spool-buffer
-;;        ps-spool-buffer-with-faces
-;;        ps-spool-region
-;;        ps-spool-region-with-faces
-;;
-;; These commands all perform essentially the same function: they
-;; generate PostScript images suitable for printing on a PostScript
-;; printer or displaying with GhostScript.  These commands are
-;; collectively referred to as "ps-print- commands".
-;;
-;; The word "print" or "spool" in the command name determines when the
-;; PostScript image is sent to the printer:
-;;
-;;        print      - The PostScript image is immediately sent to the
-;;                     printer;
-;;
-;;        spool      - The PostScript image is saved temporarily in an
-;;                     Emacs buffer.  Many images may be spooled locally
-;;                     before printing them.  To send the spooled images
-;;                     to the printer, use the command `ps-despool'.
-;;
-;; The spooling mechanism was designed for printing lots of small
-;; files (mail messages or netnews articles) to save paper that would
-;; otherwise be wasted on banner pages, and to make it easier to find
-;; your output at the printer (it's easier to pick up one 50-page
-;; printout than to find 50 single-page printouts).
-;; 
-;; Ps-print has a hook in the `kill-emacs-hooks' so that you won't
-;; accidentally quit from Emacs while you have unprinted PostScript
-;; waiting in the spool buffer.  If you do attempt to exit with
-;; spooled PostScript, you'll be asked if you want to print it, and if
-;; you decline, you'll be asked to confirm the exit; this is modeled
-;; on the confirmation that Emacs uses for modified buffers.
-;;
-;; The word "buffer" or "region" in the command name determines how
-;; much of the buffer is printed:
-;;
-;;        buffer     - Print the entire buffer.
-;;
-;;        region     - Print just the current region.
-;;
-;; The -with-faces suffix on the command name means that the command
-;; will include font, color, and underline information in the
-;; PostScript image, so the printed image can look as pretty as the
-;; buffer.  The ps-print- commands without the -with-faces suffix
-;; don't include font, color, or underline information; images printed
-;; with these commands aren't as pretty, but are faster to generate.
-;;
-;; Two ps-print- command examples:
-;;
-;;        ps-print-buffer             - print the entire buffer,
-;;                                      without font, color, or
-;;                                      underline information, and
-;;                                      send it immediately to the
-;;                                      printer.
-;;
-;;        ps-spool-region-with-faces  - print just the current region;
-;;                                      include font, color, and
-;;                                      underline information, and
-;;                                      spool the image in Emacs to
-;;                                      send to the printer later.
-;;
-;;
-;; Invoking Ps-Print
-;; -----------------
-;;
-;; To print your buffer, type
-;;
-;;        M-x ps-print-buffer
-;;
-;; or substitute one of the other seven ps-print- commands.  The
-;; command will generate the PostScript image and print or spool it as
-;; specified.  By giving the command a prefix argument
-;;
-;;        C-u M-x ps-print-buffer
-;;
-;; it will save the PostScript image to a file instead of sending it
-;; to the printer; you will be prompted for the name of the file to
-;; save the image to.  The prefix argument is ignored by the commands
-;; that spool their images, but you may save the spooled images to a
-;; file by giving a prefix argument to `ps-despool':
-;;
-;;        C-u M-x ps-despool
-;;
-;; When invoked this way, `ps-despool' will prompt you for the name of
-;; the file to save to.
-;;
-;; Any of the `ps-print-' commands can be bound to keys; I recommend
-;; binding `ps-spool-buffer-with-faces', `ps-spool-region-with-faces',
-;; and `ps-despool'.  Here are the bindings I use on my Sun 4 keyboard:
-;;
-;;   (global-set-key 'f22 'ps-spool-buffer-with-faces) ;f22 is prsc
-;;   (global-set-key '(shift f22) 'ps-spool-region-with-faces)
-;;   (global-set-key '(control f22) 'ps-despool)
-;;
-;;
-;; The Printer Interface
-;; ---------------------
-;;
-;; The variables `ps-lpr-command' and `ps-lpr-switches' determine what
-;; command is used to send the PostScript images to the printer, and
-;; what arguments to give the command.  These are analogous to
-;; `lpr-command' and `lpr-switches'.
-;;
-;; Make sure that they contain appropriate values for your system;
-;; see the usage notes below and the documentation of these variables.
-;;
-;; NOTE: `ps-lpr-command' and `ps-lpr-switches' take their initial values
-;;       from the variables `lpr-command' and `lpr-switches'.  If you have
-;;       `lpr-command' set to invoke a pretty-printer such as `enscript',
-;;       then ps-print won't work properly.  `ps-lpr-command' must name
-;;       a program that does not format the files it prints.
-;;
-;;
-;; The Page Layout
-;; ---------------
-;;
-;; All dimensions are floats in PostScript points.
-;; 1 inch  ==       2.54  cm    ==     72       points
-;; 1 cm    ==  (/ 1 2.54) inch  ==  (/ 72 2.54) points
-;;
-;; The variable `ps-paper-type' determines the size of paper ps-print
-;; formats for; it should contain one of the symbols:
-;; `a4' `a3' `letter' `legal' `letter-small' `tabloid'
-;; `ledger' `statement' `executive' `a4small' `b4' `b5'
-;;
-;; The variable `ps-landscape-mode' determines the orientation
-;; of the printing on the page:
-;; nil means `portrait' mode, non-nil means `landscape' mode.
-;; There is no oblique mode yet, though this is easy to do in ps.
-
-;; In landscape mode, the text is NOT scaled: you may print 70 lines
-;; in portrait mode and only 50 lignes in landscape mode.
-;; The margins represent margins in the printed paper:
-;; the top margin is the margin between the top of the page
-;; and the printed header, whatever the orientation is.
-;;
-;; The variable `ps-number-of-columns' determines the number of columns
-;; both in landscape and portrait mode.
-;; You can use:
-;; - (the standard) one column portrait mode
-;; - (my favorite) two columns landscape mode (which spares trees)
-;; but also
-;; - one column landscape mode for files with very long lines.
-;; - multi-column portrait or landscape mode
-;;
-;;
-;; Horizontal layout
-;; -----------------
-;;
-;; The horizontal layout is determined by the variables
-;; `ps-left-margin' `ps-inter-column' `ps-right-margin'
-;; as follows:
-;;
-;;  ------------------------------------------
-;;  |    |      |    |      |    |      |    |
-;;  | lm | text | ic | text | ic | text | rm |
-;;  |    |      |    |      |    |      |    |
-;;  ------------------------------------------
-;;
-;; If `ps-number-of-columns' is 1, `ps-inter-column' is not relevant.
-;; Usually, lm = rm > 0 and ic = lm
-;; If (ic < 0), the text of adjacent columns can overlap.
-;;
-;;
-;; Vertical layout
-;; ---------------
-;;
-;; The vertical layout is determined by the variables
-;; `ps-bottom-margin' `ps-top-margin' `ps-header-offset'
-;; as follows:
-;;
-;; |--------|        |--------|
-;; | tm     |        | tm     |
-;; |--------|        |--------|
-;; | header |        |        |
-;; |--------|        |        |
-;; | ho     |        |        |
-;; |--------|   or   | text   |
-;; |        |        |        |
-;; | text   |        |        |
-;; |        |        |        |
-;; |--------|        |--------|
-;; | bm     |        | bm     |
-;; |--------|        |--------|
-;;
-;; If `ps-print-header' is nil, `ps-header-offset' is not relevant.
-;; The margins represent margins in the printed paper:
-;; the top margin is the margin between the top of the page
-;; and the printed header, whatever the orientation is.
-;;
-;;
-;; Headers
-;; -------
-;;
-;; Ps-print can print headers at the top of each column; the default
-;; headers contain the following four items: on the left, the name of
-;; the buffer and, if the buffer is visiting a file, the file's
-;; directory; on the right, the page number and date of printing.
-;; The default headers look something like this:
-;;
-;;     ps-print.el                                         1/21
-;;     /home/jct/emacs-lisp/ps/new                     94/12/31
-;; 
-;; When printing on duplex printers, left and right are reversed so
-;; that the page numbers are toward the outside (cf. `ps-spool-duplex').
-;;
-;; Headers are configurable:
-;; To turn them off completely, set `ps-print-header' to nil.
-;; To turn off the header's gaudy framing box,
-;; set `ps-print-header-frame' to nil.
-;;
-;; The font family and size of text in the header are determined
-;; by the variables `ps-header-font-family', `ps-header-font-size' and 
-;; `ps-header-title-font-size' (see below).
-;;
-;; The variable `ps-header-line-pad' determines the portion of a header
-;; title line height to insert between the header frame and the text
-;; it contains, both in the vertical and horizontal directions:
-;; .5 means half a line.
-
-;; Page numbers are printed in `n/m' format, indicating page n of m pages;
-;; to omit the total page count and just print the page number,
-;; set `ps-show-n-of-n' to nil.
-;;
-;; The amount of information in the header can be changed by changing
-;; the number of lines.  To show less, set `ps-header-lines' to 1, and
-;; the header will show only the buffer name and page number.  To show
-;; more, set `ps-header-lines' to 3, and the header will show the time of
-;; printing below the date.
-;;
-;; To change the content of the headers, change the variables
-;; `ps-left-header' and `ps-right-header'.
-;; These variables are lists, specifying top-to-bottom the text
-;; to display on the left or right side of the header.
-;; Each element of the list should be a string or a symbol.
-;; Strings are inserted directly into the PostScript arrays,
-;; and should contain the PostScript string delimiters '(' and ')'.
-;;
-;; Symbols in the header format lists can either represent functions
-;; or variables.  Functions are called, and should return a string to
-;; show in the header.  Variables should contain strings to display in
-;; the header.  In either case, function or variable, the PostScript
-;; string delimiters are added by ps-print, and should not be part of
-;; the returned value.
-;;
-;; Here's an example: say we want the left header to display the text
-;;
-;;     Moe
-;;     Larry
-;;     Curly
-;;
-;; where we have a function to return "Moe"
-;;
-;;     (defun moe-func ()
-;;       "Moe")
-;;
-;; a variable specifying "Larry"
-;;
-;;     (setq larry-var "Larry")
-;;
-;; and a literal for "Curly".  Here's how `ps-left-header' should be
-;; set:
-;;
-;;     (setq ps-left-header (list 'moe-func 'larry-var "(Curly)"))
-;;
-;; Note that Curly has the PostScript string delimiters inside his
-;; quotes -- those aren't misplaced lisp delimiters!
-;;
-;; Without them, PostScript would attempt to call the undefined
-;; function Curly, which would result in a PostScript error.
-;;
-;; Since most printers don't report PostScript errors except by
-;; aborting the print job, this kind of error can be hard to track down.
-;;
-;; Consider yourself warned!
-;;
-;;
-;; Duplex Printers
-;; ---------------
-;;
-;; If you have a duplex-capable printer (one that prints both sides of
-;; the paper), set `ps-spool-duplex' to t.
-;; Ps-print will insert blank pages to make sure each buffer starts
-;; on the correct side of the paper.
-;; Don't forget to set `ps-lpr-switches' to select duplex printing
-;; for your printer.
-;;
-;; 
-;; Font managing
-;; -------------
-;;
-;; Ps-print now knows rather precisely some fonts:
-;; the variable `ps-font-info-database' contains information
-;; for a list of font families (currently mainly `Courier' `Helvetica'
-;; `Times' `Palatino' `Helvetica-Narrow' `NewCenturySchlbk').
-;; Each font family contains the font names for standard, bold, italic
-;; and bold-italic characters, a reference size (usually 10) and the
-;; corresponding line height, width of a space and average character width.
-;; 
-;; The variable `ps-font-family' determines which font family
-;; is to be used for ordinary text.
-;; If its value does not correspond to a known font family,
-;; an error message is printed into the `*Messages*' buffer,
-;; which lists the currently available font families.
-;;
-;; The variable `ps-font-size' determines the size (in points)
-;; of the font for ordinary text, when generating Postscript.
-;; Its value is a float.
-;;
-;; Similarly, the variable `ps-header-font-family' determines
-;; which font family is to be used for text in the header.
-;; The variable `ps-header-font-size' determines the font size,
-;; in points, for text in the header.
-;; The variable `ps-header-title-font-size' determines the font size,
-;; in points, for the top line of text in the header.
-;;
-;;
-;; Adding a new font family
-;; ------------------------
-;;
-;; To use a new font family, you MUST first teach ps-print
-;; this font, i.e., add its information to `ps-font-info-database',
-;; otherwise ps-print cannot correctly place line and page breaks.
-;;
-;; For example, assuming `Helvetica' is unknown,
-;; you first need to do the following ONLY ONCE:
-;;
-;; - create a new buffer
-;; - generate the PostScript image to a file (C-u M-x ps-print-buffer)
-;; - open this file and find the line:
-;;	`% 3 cm 20 cm moveto  10 /Courier ReportFontInfo  showpage'
-;; - delete the leading `%' (which is the Postscript comment character)
-;; - replace in this line `Courier' by the new font (say `Helvetica')
-;;   to get the line:
-;;	`3 cm 20 cm moveto  10 /Helvetica ReportFontInfo  showpage'
-;; - send this file to the printer (or to ghostscript).
-;;   You should read the following on the output page:
-;;
-;;     For Helvetica 10 point, the line height is 11.56, the space width is 2.78
-;;     and a crude estimate of average character width is 5.09243
-;;
-;; - Add these values to the `ps-font-info-database':
-;;   (setq ps-font-info-database
-;;	 (append
-;;	  '((Helvetica ; the family name
-;;	    "Helvetica" "Helvetica-Bold" "Helvetica-Oblique" "Helvetica-BoldOblique"
-;;	    10.0 11.56 2.78 5.09243))
-;;	  ps-font-info-database))
-;; - Now you can use this font family with any size:
-;;	(setq ps-font-family 'Helvetica)
-;; - if you want to use this family in another emacs session, you must
-;;   put into your `~/.emacs':
-;;	(require 'ps-print)
-;;	(setq ps-font-info-database (append ...)))
-;;   if you don't want to load ps-print, you have to copy the whole value:
-;;	(setq ps-font-info-database '(<your stuff> <the standard stuff>))
-;;   or, if you can wait until the `ps-print-hook' is implemented, do:
-;;      (add-hook 'ps-print-hook '(setq ps-font-info-database (append ...)))
-;;      This does not work yet, since there is no `ps-print-hook' yet.
-;;
-;; You can create new `mixed' font families like:
-;;	(my-mixed-family
-;;	 "Courier-Bold" "Helvetica"
-;;	 "Zapf-Chancery-MediumItalic" "NewCenturySchlbk-BoldItalic"
-;;	 10.0 10.55 6.0 6.0)
-;; Now you can use your new font family with any size:
-;;	(setq ps-font-family 'my-mixed-family)
-;;
-;; You can get information on all the fonts resident in YOUR printer
-;; by uncommenting the line:
-;;	% 3 cm 20 cm moveto  ReportAllFontInfo           showpage
-;;
-;; The postscript file should be sent to YOUR postscript printer.
-;; If you send it to ghostscript or to another postscript printer,
-;; you may get slightly different results.
-;; Anyway, as ghostscript fonts are autoload, you won't get
-;; much font info.
-;;
-;;
-;; How Ps-Print Deals With Faces
-;; -----------------------------
-;;
-;; The ps-print-*-with-faces commands attempt to determine which faces
-;; should be printed in bold or italic, but their guesses aren't
-;; always right.  For example, you might want to map colors into faces
-;; so that blue faces print in bold, and red faces in italic.
-;;
-;; It is possible to force ps-print to consider specific faces bold or
-;; italic, no matter what font they are displayed in, by setting the
-;; variables `ps-bold-faces' and `ps-italic-faces'.  These variables
-;; contain lists of faces that ps-print should consider bold or
-;; italic; to set them, put code like the following into your .emacs
-;; file:
-;;
-;; 	(setq ps-bold-faces '(my-blue-face))
-;;      (setq ps-italic-faces '(my-red-face))
-;;
-;; Faces like bold-italic that are both bold and italic should go in
-;; *both* lists.
-;;
-;; Ps-print keeps internal lists of which fonts are bold and which are
-;; italic; these lists are built the first time you invoke ps-print.
-;; For the sake of efficiency, the lists are built only once; the same
-;; lists are referred in later invocations of ps-print.
-;;
-;; Because these lists are built only once, it's possible for them to
-;; get out of sync, if a face changes, or if new faces are added.  To
-;; get the lists back in sync, you can set the variable
-;; `ps-build-face-reference' to t, and the lists will be rebuilt the
-;; next time ps-print is invoked.
-;;
-;;
-;; How Ps-Print Deals With Color
-;; -----------------------------
-;;
-;; Ps-print detects faces with foreground and background colors
-;; defined and embeds color information in the PostScript image.
-;; The default foreground and background colors are defined by the
-;; variables `ps-default-fg' and `ps-default-bg'.
-;; On black-and-white printers, colors are displayed in grayscale.
-;; To turn off color output, set `ps-print-color-p' to nil.
-;;
-;;
-;; Utilities
-;; ---------
-;;
-;; Some tools are provided to help you customize your font setup.
-;;
-;; `ps-setup' returns (some part of) the current setup.
-;;
-;; To avoid wrapping too many lines, you may want to adjust the
-;; left and right margins and the font size.  On UN*X systems, do:
-;; pr -t file | awk '{printf "%3d %s\n", length($0), $0}' | sort -r | head
-;; to determine the longest lines of your file.
-;; Then, the command `ps-line-lengths' will give you the correspondence
-;; between a line length (number of characters) and the maximum font
-;; size which doesn't wrap such a line with the current ps-print setup.
-;;
-;; The commands `ps-nb-pages-buffer' and `ps-nb-pages-region' display
-;; the correspondence between a number of pages and the maximum font
-;; size which allow the number of lines of the current buffer or of
-;; its current region to fit in this number of pages.
-;; Note: line folding is not taken into account in this process
-;; and could change the results.
-;;
-;;
-;; New since version 1.5
-;; ---------------------
-;;
-;; Color output capability.
-;; Automatic detection of font attributes (bold, italic).
-;; Configurable headers with page numbers.
-;; Slightly faster.
-;; Support for different paper sizes.
-;; Better conformance to PostScript Document Structure Conventions.
-;;
-;;
-;; New since version 2.8
-;; ---------------------
-;;
-;; [jack] 960517 Jacques Duthen <duthen@cegelec-red.fr>
-;;
-;; Font familiy and float size for text and header.
-;; Landscape mode.
-;; Multiple columns.
-;; Tools for page setup.
-;;
-;;
-;; Known bugs and limitations of ps-print:
-;; --------------------------------------
-;;
-;; Although color printing will work in XEmacs 19.12, it doesn't work
-;; well; in particular, bold or italic fonts don't print in the right
-;; background color.
-;;
-;; Invisible properties aren't correctly ignored in XEmacs 19.12.
-;;
-;; Automatic font-attribute detection doesn't work well, especially
-;; with hilit19 and older versions of get-create-face.  Users having
-;; problems with auto-font detection should use the lists
-;; `ps-italic-faces' and `ps-bold-faces' and/or turn off automatic
-;; detection by setting `ps-auto-font-detect' to nil.
-;;
-;; Automatic font-attribute detection doesn't work with XEmacs 19.12
-;; in tty mode; use the lists `ps-italic-faces' and `ps-bold-faces'
-;; instead.
-;;
-;; Still too slow; could use some hand-optimization.
-;;
-;; ASCII Control characters other than tab, linefeed and pagefeed are
-;; not handled.
-;;
-;; Default background color isn't working.
-;;
-;; Faces are always treated as opaque.
-;;
-;; Epoch and Emacs 18 not supported.  At all.
-;;
-;; Fixed-pitch fonts work better for line folding, but are not required.  
-;;
-;; `ps-nb-pages-buffer' and `ps-nb-pages-region' don't take care
-;; of folding lines.
-;;
-;;
-;; Things to change:
-;; ----------------
-;;
-;; Add `ps-print-hook' (I don't know how to do that (yet!)).
-;; Add 4-up capability (really needed?).
-;; Add line numbers (should not be too hard).
-;; Add `ps-non-bold-faces' and `ps-non-italic-faces' (should be easy).
-;; Put one header per page over the columns (easy but needed?).
-;; Improve the memory management for big files (hard?).
-;; `ps-nb-pages-buffer' and `ps-nb-pages-region' should take care
-;; of folding lines.
