gambc

Gambit Scheme interpreter and compiler

The gambc package includes a Scheme interpreter and a Scheme compiler which can be used to build standalone executables. The thread system is very efficient and can support millions of concurrent processes. The Gambit system conforms to the R4RS, R5RS and IEEE Scheme standards. The full numeric tower is implemented, including: infinite precision integers (bignums), rationals, inexact reals (floating point numbers), and complex numbers. Gambit supports a number of extensions to the standards.

ghostscript

Ghostscript is a set of software that provides a PostScript

interpreter, a set of C procedures (the Ghostscript library, which implements the graphics capabilities in the PostScript language) and an interpreter for Portable Document Format (PDF) files. Ghostscript translates PostScript code into many common, bitmapped formats, like those understood by your printer or screen. Ghostscript is normally used to display PostScript files and to print PostScript files to non-PostScript printers. If you need to display PostScript files or print them to non-PostScript printers, you should install ghostscript. If you install ghostscript, you also need to install the ghostscript-fonts package.
