"""CLAPACK is a f2c'ed version of LAPACK.
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."""
