singular: Computer algebra system for polynomial computations, algebraic geometry, singularity theory
=====================================================================================================

Description

special emphasis on commutative and non-commutative algebra, algebraic
geometry, and singularity theory.

Special Update/Build Instructions
---------------------------------

Other notes:

-  If the environment variable SAGE_DEBUG is set to "yes", then
   omalloc will be replaced by xalloc. The resulting Singular executable
   and libsingular library will be slower than with omalloc, but allow
   for easier debugging of memory corruptions.
