+# Autoconf macro for working with GNUnet

+# Find the GNUnet installation, either automatically or through the
+# --with-gnunet-prefix flag
+#
+# This macro runs the pkg-config and, if needed, the gnunet-config tool
+# provided by GNUnet itself.
+#
+# The gnunet-config tool can be overridden by setting the GNUNET_CONFIG
+# variable before executing the configure script.
+#
+# The variables GNUNET_CFLAGS and GNUNET_LIBS will be set to appropriate
+# values and are made available to Automake.
