Welcome to Ghostscript, an interpreter for the PostScript language and for PDF.
The leading edge of Ghostscript development is now under GPL license, as is the latest release, Ghostscript 8.62.
Ghostscript can be downloaded here, and from cs.wisc.edu and sourceforge.net.
We keep online documentation for the development tree and many previous releases in the documentation archive.
