%description
The CLAPACK library was built using a Fortran to C conversion utility
called f2c.  The entire Fortran 77 LAPACK library is run through f2c to
obtain C code, and then modified to improve readability.  CLAPACK's goal
is to provide LAPACK for someone who does not have access to a Fortran
compiler.
