-;; Merge 31 diffs between 19.29 and 19.34
-
-;; 3.02 [jack] June 26, 1996 Jacques Duthen <[email protected]>
-;; Add new page dimensions to `ps-page-dimensions-database' for `paper-type'
-;; Improve landscape mode `ps-landscape-mode' and multiple columns
-;; printing `ps-number-of-columns':
-;; The text and the margins are no more scaled.
-;; Simplify the semantics of `ps-inter-column' (space between columns).
-;; Add error checking for negative `ps-print-width' and `ps-print-height'.
-;; Change the semantics of `ps-top-margin' which is now the TOP MARGIN,
-;; and add `ps-header-offset' instead of having `ps-top-margin' split in 2.
-;; Add `ps-header-font-family', `ps-header-font-size' and 
-;; `ps-header-title-font-size' to control the header.
-;; Add `ps-header-line-pad'.
-;; Change the semantics of `ps-font-info-database' to have symbolic
-;; font families.
-;; Add new fonts to `ps-font-info-database': `Courier' `Helvetica'
-;; `Times' `Palatino' `Helvetica-Narrow' `NewCenturySchlbk'
-;; Make public `ps-font-family' and `ps-font-size' so that the user
-;; can directly control the text font and size without loading ps-print.
-;; Add error checking for unknown font families and a message giving
-;; the exhaustive list of available font families.
-;; Document how to install a new font family.
-;; Add `/ReportAllFontInfo' to get all the font families of the printer.
-;; Add the possibility to make `mixed' font families.
-;; Add `ps-setup' to get the current setup.
-;; Add tools `ps-line-lengths' `ps-nb-pages-buffer' `ps-nb-pages-region'
-;; to help choose the font size.
-;; Split `ps-print-prologue' in two to insert info from header fonts
-;; Replace indexes by macro `ps-page-dimensions-get-width'
-;; to get access to the dimensions list.
-;; Add `ps-select-font' inside `ps-get-page-dimensions'.
-;; Fix the "clumsy" `ps-page-height' management.
-;; Move `ps-get-page-dimensions' to the beginning of `ps-begin-file'
-;; to get early error checking.
-;; Add sample setup `ps-jack-setup'.
-;;
-;; Rewrite a lot of postscript code and add comments inside it
-;; (maybe they should not (or optionally) be included in the generated
-;; Postscript).
-;; Translate the origin to (lm, bm) to simplify the other moves.
-;; Fix bug in `/HeaderOffset' with `/PrintStartY'.
-;; Fix bug in `/SetHeaderLines'.
-;; Change `/ReportFontInfo' for use by `/ReportAllFontInfo'.

-;; 3.01 [jack] June 4, 1996 Jacques Duthen <[email protected]>

-
-;; 3.00 [jack] May 17, 1996 Jacques Duthen <[email protected]>
