- ********
- ******** 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, which in turn bears a
- considerable resemblance to Forth; 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 some platforms.
- Currently, Ghostscript is known to run on two platform families:
-
- - IBM PC and compatibles with EGA or compatible graphics
- (256K frame buffer required) under MS-DOS 3.1, and
-
- - Sun-3 and Sun-4 under SunOS 4.0, with X Windows version 11,
- release 3.
-
- 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. The Unix implementation has poor
- performance, because the interface between the Ghostscript library
- and its back end is low-level and does not take advantage of many of
- the facilities provided by X: we intend that this will change sometime
- in the future.
