%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.

* Sat Jun 11 2022 Andrew Savchenko <bircoph@altlinux.org> 3.2.1-alt2.E2K.3
- Use system libf2c-ng
* Mon Jun 06 2022 Andrew Savchenko <bircoph@altlinux.org> 3.2.1-alt2.E2K.2
- Disable xblas if Fortran is disabled: reduced xblas C-only
implementation is not sufficient for clapack.
