 +# SYNOPSIS
 +#
-+#   ACX_BLAS([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
++#   AX_BLAS([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
 +#
 +# DESCRIPTION
 +#
-+#   This macro looks for a library that implements the BLAS
-+#   linear-algebra interface (see http://www.netlib.org/blas/). On
-+#   success, it sets the BLAS_LIBS output variable to hold the
-+#   requisite library linkages.
++#   This macro looks for a library that implements the BLAS linear-algebra
++#   interface (see http://www.netlib.org/blas/). On success, it sets the
++#   BLAS_LIBS output variable to hold the requisite library linkages.
 +#
 +#   To link with BLAS, you should link with:
 +#
-+#   	$BLAS_LIBS $LIBS $FLIBS
++#     $BLAS_LIBS $LIBS $FLIBS
 +#
 +#   in that order. 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.

++#   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.
 +#
-+#   Many libraries are searched for, from ATLAS to CXML to ESSL. The
-+#   user may also use --with-blas=<lib> in order to use some specific
-+#   BLAS 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
-+#   BLAS library.

++#   will probably need to use the same Fortran compiler (which can be set

 +#
-+#   ACTION-IF-FOUND is a list of shell commands to run if a BLAS
-+#   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_BLAS.

++#   define HAVE_BLAS.

-+#   This macro requires autoconf 2.50 or later.

-+#   ACX_LAPACK([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
++#   AX_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.
++#   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.
++#     $LAPACK_LIBS $BLAS_LIBS $LIBS $FLIBS
 +#
-+#   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.
++#   in that order. BLAS_LIBS is the output variable of the AX_BLAS macro,
++#   called automatically. FLIBS is the output variable of the
++#   AC_F77_LIBRARY_LDFLAGS macro (called if necessary by AX_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.
 +#
-+#   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.
++#   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.
 +#
-+# LAST MODIFICATION
++#   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.
