+# 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.

+# 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.
