Ghostscript is a suite of software based on an interpreter for Adobe Systems' PostScript and Portable Document Format (PDF) page description languages. Its main purposes are the rasterization or rendering of such page description language files, for the display or printing of document pages, and the conversion between PostScript and PDF files.
Steles are the tools used by Shadowhunters to draw runes onto their skin, weapons, and other materials. They are made of adamas and crafted by the Iron Sisters.
Steles are found at nearly every significant mountain and historical site in China. The First Emperor made five tours of his domain in the 3rd century BC and had Li Si make seven stone inscriptions commemorating and praising his work, of which fragments of two survive.
