                      What's new in GNU enscript
                      --------------------------

Noteworthy changes in enscript version 1.6.3:

* Changes in the highlighting / pretty printing

  - The `States*' config file options have changed.  The new options
    are:
      - StatesBinary            specify an absolute path for `states'
      - StatesColor             use colors in the highlighting outputs?
      - StatesConfigFile        config file name (enscript.st)
      - StatesHighlightStyle    highlighting style
      - StatesPath              path from which the states is looking
                                up the state definition files (.st)

  - Support for user defined local highlighting definitions and styles.
  - new option `--style=STYLE' to specify the highlighting style
  - Verbose highlighting for the C, C++, and Objective-C languages.
    In the verbose highlighting, some mathematical constructs (&&, ||,
    !=, etc.) are replaced with the corresponding mathematical symbols
    (logical and, logical or, not equal, etc.).  The mode can be
    enabled with option `--style=emacs_verbose'.
  - renamed `--pretty-print' and `--help-pretty-print' options to
    `--highlight' and `--help-highlight'

* states:

  - Support for state inheritance.

* new highlighting rules:

  - bash, csh, ksh, tcsh, zsh
                Unix shells
  - m4          m4 macro preprocessor
  - skill       Cadence Design Systems lispy language
  - vrml        Virtual Reality Modeling Language (VRML97)
  - rfc         fix broken page breaks in RFCs and in Internet Drafts
  - inf         GUI INF Script language
  - matlab      Matlab files
  - outline     Emacs' outline text
  - tex         TeX/LaTeX source files.
  - diffs       side diff files
  - fortran_pp  fortran 77 with preprocessor
  - wmlscript   WMLScript language

  - new output language `ansi' to print color outputs on color xterm,
    etc.

* new encodings:

  - 88599       ISO-8859-9 (ISO Latin5)
  - 885910      ISO-8859-10 (ISO Latin6)

* new options:

  - -3, -4, -5, -6, -7, -8, -9  select 3-9 columns
  - --nup-columnwise            layout pages in the N-up printing
                                columnwise
  - --swap-even-page-margins    swap left and right side margins for
                                even numbered pages
  - --extended-return-values    encode more status information in the
                                return value of the program
  - --footer=STRING             specify the page footer string

* misc:

  - It is possible to specify the font encoding in the ^@font{}
    escape.  But, it allows only `ps' or the enscript's global input
    encoding values.  For example, ^@font{Symbol@7:ps}b^@font{default}
    prints the beta symbol
  - New escape ^@bgcolor{} to change the text background color.
  - New fancy headers `squeeze' and `enscript-color'.
  - Minor fixes in the 88593 and 88594 encodings.
  - New highlighting style `msvc'.
  - Support for the matrix printers.  Try `enscript -fMatrix10' ;-)
  - Fixed some buffer overrun bugs.  Now all buffer space for unknown
    items (filenames, user-supplied tokens, etc.) is allocated
    dynamically.
  - Removed the `--list-options' option.  It was an old debugging
    option.  I can remember when I have used or updated it.

Noteworthy changes in enscript version 1.3:

* new encodings:
  - 88593       ISO-8859-3
  - pslatin1    PostScript interpreter's ISOLatin1Encoding

* new fancy header: edd, a2ps

* option changes:
  - option -Z, --pass-through-ps-files no longer wraps PS document
    inside enscript prolog and epilog.

  - renamed some options to conform the GNU coding standards:
      --output-file     =>      --output
      --queue           =>      --printer
      --tab-size        =>      --tabsize

  - new command line / config file options:
    -z, --no-formfeed
    --ul-angle                  UnderlayAngle
    --ul-position               UnderlayPosition
    --non-printable-format      NonPrintableFormat

* added some customization options to header description files:
    %Format             format and define string constants according
                        to format string
    %HeaderHeight       explicit set the fancy header height
    %FooterHeight       allocate space for the page footer

  Note!  If you have defined your own fancy header, it will probably
  not work on enscript-1.3 without modifications.  Following constants
  are removed from the enscript prolog so you must define them with
  the `%Format' comment:

    usadatestr = %Format: usadatestr    %W
    eurdatestr = %Format: eurdatestr    %E
    findatestr = %Format: findatestr    %F
    timestr    = %Format: timestr       %C
    fmodstr    = %Format: fmodstr       $D{%a %b %e %T %Y}

  Check `lib/*.hdr' to see them in action.

* the library directory has changed from `<prefix>/lib/enscript' to
  `<prefix>/share/enscript'

* new Makefile targets: check, uninstall

* enscript must no longer be installed before it can be tested; you
  can print files directly after you have compiled enscript.

* support for Windows95/NT via the Win32 api
