20 * scientific software is very special. Version control is crucial -
21 * bugs must be traceable. We will be happy to consider code for
22 * inclusion in the official distribution, but derived work must not
23 * be called official GROMACS. Details are found in the README & COPYING
24 * files - if they are missing, get the official version at www.gromacs.org.

36 * Header definitions for the standard BLAS library.
38 * This is the subset of BLAS routines used for the
39 * linear algebra operations in Gromacs.
40 * Do NOT use this for other purposes - we only provide this as a
41 * simple fallback/reference implementation when no optimized BLAS
42 * is present. If you need an implementation for your own code
43 * there are several much faster versions out there.
45 * All routines are compatible with the BLAS reference implementation,
46 * meaning they assume fortran-style matrix row/column organization.
48 * There is plenty of documentation for these routines available
49 * at http://www.netlib.org/blas , so there is no point in repeating
