- An interpreter for the PostScript (TM) language and the Adobe
Portable Document Format (PDF -- sometimes confused with Acrobat,
Adobe's PDF browser/editor product), and
- A set of C procedures (the Ghostscript library) that implement
the graphics and filtering (data compression / decompression
/ conversion) capabilities that appear as primitive operations
in the PostScript language and in PDF.
