-+# 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.
