+#   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

-# ===========================================================================
-#
-# 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.
