+# ===========================================================================

+# ===========================================================================
+#
+# SYNOPSIS
+#
+# AX_LIB_HILBERT()
+#
+# DESCRIPTION
+#
+# This macro provides tests of the availability of libHilbert library.
+#
+#
+# The macro adds a --with-libhilbert option accepting one of three values:
+#
+# no - do not check for the libhilbert library.
+# yes - do check for libhilbert library in standard locations.
+# path - complete path to the libhilbert library.
+#
+# If libhilbert is successfully found, this macro calls
+#
+# AC_SUBST(LIBHILBERT_INCLUDE)
+# AC_SUBST(LIBHILBERT_LIB)
+# AC_DEFINE(HAVE_LIBHILBERT)
+#
+# and sets with_libhilbert="yes"
+#
+# If libhilbert is disabled or not found, this macros sets with_libhilbert="no"
+#
+# Your configuration script can test $with_libhilbert to take any further
+# actions. LIBHILBERT_{INCLUDE,LIB} may be used when building with C or C++.
+#
+# To use the macro, one would code one of the following in "configure.ac"
+# before AC_OUTPUT:
+#
+# 1) dnl Check for libhilbert support
+# AX_LIB_HILBERT()
+#
+# One could test $with_libhilbert for the outcome or display it as follows
+#
+# echo "libhilbert support: $with_libhilbert"
+#
+# You could also for example, override the default CC in "configure.ac"
