		      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.

    %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
