Ghostscript

Ghostscript is an interpreter for the PostScript language and for PDF, available from http://www.ghostscript.com. Ghostscript is a command-line-tool, if you need a graphical interface install GSView. Ghostscript can be a requirement of other software, for example Scribus.

Ghostscript is available either with a GPL licence, or with a commercial licence. From the Ghostscript web site: "Which license is right for me? For example, for personal use, use without redistribution, and use with no technical support the GNU Public License (GPL) download is your choice. If you are unwilling/unable to abide by the terms of the GPL (for instance, if you wish to redistribute these software packages or derivations thereof commercially), or if you wish to pay for technical support, you will need to acquire a commercial license from Artifex."

AFPL Ghostscript and ESP Ghostscript have been discontinued, their features integrated into GPL Ghostscript.

Each Ghostscript version is installed separately, when you uninstall one version it doesn't uninstall other versions.

Ghostscript 9

An improvement over Ghostscript 8, Ghostscript 9 can be silently installed directly by using the downloaded installer, and can be uninstalled silently.
