All LAPACK driver subroutines (including expert drivers) and some LAPACK
computationals have both generic LAPACK95 interfaces and generic
LAPACK77 interfaces. The remaining computationals have only generic
LAPACK77 interfaces. In both types of interfaces no distinction is made between
single and double precision or between real and complex data types. The use of
the LAPACK95 (LAPACK77) interface requires the user to specify the F95_LAPACK
(F77_LAPACK) module.
For example, the GESV driver subroutine, which solves a general
system of linear equations, can be called in the following ways:

- CALL LA_GESV( A, B, IPIV=ipiv, INFO=info ) ! F95_LAPACK is needed

- CALL LA_GESV( N, NRHS, A, LDA, IPIV, B, LDB, INFO ) ! F77_LAPACK is
needed.

The LAPACK95 library and documentation will successively be updated.
