- ********
- ******** An overview of Ghostscript ********
- ********
-
- Ghostscript is the name of a set of software that provides:
-
- - An interpreter for the Ghostscript language, which very
- closely resembles the PostScript (TM) language; and
-
- - A set of C procedures (the Ghostscript library) that
- implement the graphics capabilities that appear as primitive
- operations in the Ghostscript language.
-
- The Ghostscript language interpreter and library are written entirely
- in C, with some assembly-language accelerators for MS-DOS platforms.
- Currently, Ghostscript is known to run on the following platform
- families:
-
- - IBM PC and compatibles with EGA, VGA, or compatible graphics
- (256K frame buffer required) under MS-DOS 3.1 or 3.3;
-
- - A wide variety of Unix systems using X Windows version 11,
- release 3 and 4, including Sun-3, Sun-4, Sun-386i,
- Sun SPARCStation 1; generic 80386 machines running 386/ix;
- H-P 9000/300 and 9000/800; DECStation 2100 and 3100; VAX
- running Ultrix; Sequent Symmetry; Convex C1 and C2;
-
- - Sun workstations (Sun-3, SPARC, Sun-386i) running SunView;
-
- - VAX, VMS with X11R3, gcc and DEC C compiler (DEC C compiler
- version 3.1 or later is required).
-
- It is very likely that Ghostscript will run under other versions of
- MS-DOS, and other versions of Unix that support X11, but it has not
- been tested in these environments. Ghostscript does NOT run well on
- PC-compatibles with Hercules display cards: text and graphics output
- interfere with each other.
-
- ********
- ******** Documentation overview ********
- ********
-
- All the file names mentioned in the documentation, except for README,
- are in lower case, which is the usual convention for Unix systems.
- On MS-DOS systems, all file names are actually upper-case.
-
- Files of interest to most users (both previous and new)

-
- > README - this file.
-
- > readme.doc - information about problems and new features in the
- current release.
-
- If you have used a previous release of Ghostscript, you should also
- read any more recent sections of history.doc.

- The best times to call on the phone are 8:30-11:30 AM Monday-Friday;
- at other times you may get an answering machine. Only use the
- Internet if your organization or activity allows this -- the UUCP
- path works just as well, but may take longer.
-
- If you report a problem, please specify which version of Ghostscript
- you are running, and the hardware, operating system, window system,
- and C compiler you are using, and be as specific as you can about the
- problem -- this will help us a lot in tracking it down. We want
- Ghostscript to be a high-quality product, and will do our best to fix
- any reported problem.
-
- Aladdin Enterprises owns or has access to the following hardware and
- software:
-
- 80486 PC, MS-DOS 3.30, Borland C++ 2.0;
- color SuperVGA display, Epson-compatible printer
- (the printer also is compatible with the IBM Proprinter);
- H-P PaintJet; Canon BubbleJet
-
- SPARCstation, SunOS 4.0, cc and gcc, X11R4 and SunView;
- both monochrome and color displays
-
- DECstation, Ultrix
-
- If your problem turns out to be specific to some other hardware or
- software configuration, it may take longer to track down, since we
- will have to rely on other users to help.
