BEARCLAW stands for "Boundary Embedded Adaptive Refinement for
Conservation Laws". This is a newly developed version of AMRCLAW
designed from scratch with a uniform tree structure in 1 through 4 space
dimensions. It is written in fortran 90 and includes MPI capabilities.
The basic form of the Riemann solvers required are similar to what is
used in CLAWPACK. This code was developed primarily by Sorin Mitran
while he was at the University of Washington.
