++# SYNOPSIS
++#
++#   ACX_BLAS_F77_FUNC([ACTION-IF-PASS[, ACTION-IF-FAIL[, ACTION-IF-CROSS-COMPILING]])
++#   ACX_BLAS_WITH_F77_FUNC([ACTION-IF-FOUND-AND-PASS[, ACTION-IF-NOT-FOUND-OR-FAIL]])
++#
++# DESCRIPTION
++#
++#   These macros are intended as a supplement to the ACX_BLAS macro, to
++#   verify that BLAS functions are properly callable from Fortran. This is
++#   necessary, for example, if you want to build the LAPACK library on top
++#   of the BLAS.
++#
++#   ACX_BLAS_F77_FUNC uses the defined BLAS_LIBS and Fortran environment to
++#   check for compatibility, and takes a specific action in case of success,
++#   resp. failure, resp. cross-compilation.
++#
++#   ACX_BLAS_WITH_F77_FUNC is a drop-in replacement wrapper for ACX_BLAS
++#   that calls ACX_BLAS_F77_FUNC after detecting a BLAS library and rejects
++#   it on failure (i.e. pretends that no library was found).

++#
++# SYNOPSIS
++#
++#   ACX_LAPACK([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
++#
++# DESCRIPTION
++#
++#   This macro looks for a library that implements the LAPACK linear-algebra
++#   interface (see http://www.netlib.org/lapack/). On success, it sets the
++#   LAPACK_LIBS output variable to hold the requisite library linkages.
++#
++#   To link with LAPACK, you should link with:
++#
++#       $LAPACK_LIBS $BLAS_LIBS $LIBS $FLIBS
++#
++#   in that order. BLAS_LIBS is the output variable of the ACX_BLAS macro,
++#   called automatically. FLIBS is the output variable of the
++#   AC_F77_LIBRARY_LDFLAGS macro (called if necessary by ACX_BLAS), and is
++#   sometimes necessary in order to link with F77 libraries. Users will also
++#   need to use AC_F77_DUMMY_MAIN (see the autoconf manual), for the same
++#   reason.
++#
++#   The user may also use --with-lapack=<lib> in order to use some specific
++#   LAPACK library <lib>. In order to link successfully, however, be aware
++#   that you will probably need to use the same Fortran compiler (which can
++#   be set via the F77 env. var.) as was used to compile the LAPACK and BLAS
++#   libraries.
++#
++#   ACTION-IF-FOUND is a list of shell commands to run if a LAPACK library
++#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
++#   is not found. If ACTION-IF-FOUND is not specified, the default action
++#   will define HAVE_LAPACK.

+-# ===========================================================================
+-#
+-# SYNOPSIS
+-#
+-#   ACX_BLAS_F77_FUNC([ACTION-IF-PASS[, ACTION-IF-FAIL[, ACTION-IF-CROSS-COMPILING]])
+-#   ACX_BLAS_WITH_F77_FUNC([ACTION-IF-FOUND-AND-PASS[, ACTION-IF-NOT-FOUND-OR-FAIL]])
+-#
+-# DESCRIPTION
+-#
+-#   These macros are intended as a supplement to the ACX_BLAS macro, to
+-#   verify that BLAS functions are properly callable from Fortran. This is
+-#   necessary, for example, if you want to build the LAPACK library on top
+-#   of the BLAS.
+-#
+-#   ACX_BLAS_F77_FUNC uses the defined BLAS_LIBS and Fortran environment to
+-#   check for compatibility, and takes a specific action in case of success,
+-#   resp. failure, resp. cross-compilation.
+-#
+-#   ACX_BLAS_WITH_F77_FUNC is a drop-in replacement wrapper for ACX_BLAS
+-#   that calls ACX_BLAS_F77_FUNC after detecting a BLAS library and rejects
+-#   it on failure (i.e. pretends that no library was found).

+-#
+-# SYNOPSIS
+-#
+-#   ACX_LAPACK([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+-#
+-# DESCRIPTION
+-#
+-#   This macro looks for a library that implements the LAPACK linear-algebra
+-#   interface (see http://www.netlib.org/lapack/). On success, it sets the
+-#   LAPACK_LIBS output variable to hold the requisite library linkages.
+-#
+-#   To link with LAPACK, you should link with:
+-#
+-#       $LAPACK_LIBS $BLAS_LIBS $LIBS $FLIBS
+-#
+-#   in that order. BLAS_LIBS is the output variable of the ACX_BLAS macro,
+-#   called automatically. FLIBS is the output variable of the
+-#   AC_F77_LIBRARY_LDFLAGS macro (called if necessary by ACX_BLAS), and is
+-#   sometimes necessary in order to link with F77 libraries. Users will also
+-#   need to use AC_F77_DUMMY_MAIN (see the autoconf manual), for the same
+-#   reason.
+-#
+-#   The user may also use --with-lapack=<lib> in order to use some specific
+-#   LAPACK library <lib>. In order to link successfully, however, be aware
+-#   that you will probably need to use the same Fortran compiler (which can
+-#   be set via the F77 env. var.) as was used to compile the LAPACK and BLAS
+-#   libraries.
+-#
+-#   ACTION-IF-FOUND is a list of shell commands to run if a LAPACK library
+-#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+-#   is not found. If ACTION-IF-FOUND is not specified, the default action
+-#   will define HAVE_LAPACK.
