+# SYNOPSIS
+#
+#   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.
+#
+#   To link with BLAS, you should link with:
+#
+#     $BLAS_LIBS $LIBS $FLIBS
+#
+#   in that order. 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.
+#
+#   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.
+#
+#   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.

+# SYNOPSIS
+#
+#   AX_CODE_COVERAGE()
+#
+# DESCRIPTION
+#
+#   Defines CODE_COVERAGE_CPPFLAGS, CODE_COVERAGE_CFLAGS,
+#   CODE_COVERAGE_CXXFLAGS and CODE_COVERAGE_LIBS which should be included
+#   in the CPPFLAGS, CFLAGS CXXFLAGS and LIBS/LIBADD variables of every
+#   build target (program or library) which should be built with code
+#   coverage support. Also defines CODE_COVERAGE_RULES which should be
+#   substituted in your Makefile; and $enable_code_coverage which can be
+#   used in subsequent configure output. CODE_COVERAGE_ENABLED is defined
+#   and substituted, and corresponds to the value of the
+#   --enable-code-coverage option, which defaults to being disabled.
+#
+#   Test also for gcov program and create GCOV variable that could be
+#   substituted.
+#
+#   Note that all optimization flags in CFLAGS must be disabled when code
+#   coverage is enabled.
+#
+#   Usage example:
+#
+#   configure.ac:
+#
+#     AX_CODE_COVERAGE
+#
+#   Makefile.am:
+#
+#     @CODE_COVERAGE_RULES@
+#     my_program_LIBS = ... $(CODE_COVERAGE_LIBS) ...
+#     my_program_CPPFLAGS = ... $(CODE_COVERAGE_CPPFLAGS) ...
+#     my_program_CFLAGS = ... $(CODE_COVERAGE_CFLAGS) ...
+#     my_program_CXXFLAGS = ... $(CODE_COVERAGE_CXXFLAGS) ...
+#
+#   This results in a "check-code-coverage" rule being added to any
+#   Makefile.am which includes "@CODE_COVERAGE_RULES@" (assuming the module
+#   has been configured with --enable-code-coverage). Running `make
+#   check-code-coverage` in that directory will run the module's test suite
+#   (`make check`) and build a code coverage report detailing the code which
+#   was touched, then print the URI for the report.
+#
+#   In earlier versions of this macro, CODE_COVERAGE_LDFLAGS was defined
+#   instead of CODE_COVERAGE_LIBS. They are both still defined, but use of
+#   CODE_COVERAGE_LIBS is preferred for clarity; CODE_COVERAGE_LDFLAGS is
+#   deprecated. They have the same value.
+#
+#   This code was derived from Makefile.decl in GLib, originally licenced
+#   under LGPLv2.1+.

+# SYNOPSIS
+#
+#   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.
+#
+#   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 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.
+#
+#   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.
