++PySparse: A Fast Sparse Matrix Library for Python
++=================================================

++Documentation is available in the docstrings and
++online at http://pysparse.sourceforge.net/.

++Contents

++Pysparse imports
++::
++ spmatrix                     --- sparse matrix types
++
++and, in addition, provides:
++    
++Subpackages
++-----------
++Using any of these subpackages requires an explicit import.  For example,
++``import pysparse.itsolvers``.
++
++::
++
++ itsolvers                    --- Iterative linear algebra solvers
++ precon                       --- Preconditioners
++ direct                       --- Direct solvers
++ direct.superlu               --- Wrappers to SuperLU library
++ direct.umfpack               --- Wrappers to UMFPACK library
++ eigen.jdsym                  --- Jacobi davidson eigenvalue solver for symmetric matrices
