<mathematics, tool> A package for symbolic mathematics, especially tensor analysis and General Relativity, developed by Inge Frick in Stockholm in the late 1970s to early 1980s. SHEEP was implemented in DEC-10 assembly language, then in several LISPs. The current version runs on Sun-3 and is based on Portable Standard LISP.
