+dnl Provides option to change library probes.
+dnl
+dnl This file provides RRA_ENABLE_REDUCED_DEPENDS, which adds the configure
+dnl option --enable-reduced-depends to request that library probes assume
+dnl shared libraries are in use and dependencies of libraries should not be
+dnl probed.  If this option is given, the shell variable rra_reduced_depends
+dnl is set to true; otherwise, it is set to false.
+dnl
+dnl This macro doesn't do much but is defined separately so that other macros
+dnl can require it with AC_REQUIRE.
+dnl
+dnl The canonical version of this file is maintained in the rra-c-util
+dnl package, available at <http://www.eyrie.org/~eagle/software/rra-c-util/>.
