 23                 (logical and, logical or, not equal, etc.).  The mode can be

 73             
 74               - It is possible to specify the font encoding in the ^@font{}
 75                 escape.  But, it allows only `ps' or the enscript's global input
 76                 encoding values.  For example, ^@font{Symbol@7:ps}b^@font{default}
 77                 prints the beta symbol
 78               - New escape ^@bgcolor{} to change the text background color.

 84                 items (filenames, user-supplied tokens, etc.) is allocated
 85 rizwank 1.1     dynamically.
 86               - Removed the `--list-options' option.  It was an old debugging
 87                 option.  I can remember when I have used or updated it.
 88               - Renamed `-W' to `-w'.

299                   --output-file	=> 	--output
300                   --queue		=>	--printer
301                   --tab-size	=>	--tabsize
302             
303               - new command line / config file options:
304                 -z, --no-formfeed
305                 --ul-angle			UnderlayAngle
306                 --ul-position		UnderlayPosition
307                 --non-printable-format	NonPrintableFormat
308             
309             * added some customization options to header description files:
310                 %Format		format and define string constants according
311             			to format string
312                 %HeaderHeight	explicit set the fancy header height
313                 %FooterHeight	allocate space for the page footer
314             
315               Note!  If you have defined your own fancy header, it will probably
316 rizwank 1.1   not work on enscript-1.3 without modifications.  Following constants
317               are removed from the enscript prolog so you must define them with
318               the `%Format' comment:
319             
320                 usadatestr = %Format: usadatestr	%W
321                 eurdatestr = %Format: eurdatestr	%E
322                 findatestr = %Format: findatestr	%F
323                 timestr    = %Format: timestr	%C
324                 fmodstr    = %Format: fmodstr	$D{%a %b %e %T %Y}
325             
326               Check `lib/*.hdr' to see them in action.
327             
328             * the library directory has changed from `<prefix>/lib/enscript' to
329               `<prefix>/share/enscript'
330             
331             * new Makefile targets: check, uninstall
332             
333             * enscript must no longer be installed before it can be tested; you
334               can print files directly after you have compiled enscript.
335             
336             * support for Windows95/NT via the Win32 api
