+Software available on this web site contains cryptography and is

+payment. Object code resulting from the compiling of such source code
+may also be exported and reexported under this provision if publicly
+available and not subject to a fee or payment other than reasonable
+and customary fees for reproduction and distribution. This kind of
+encryption source code and the corresponding object code may be
+exported or reexported without prior U.S. government export license
+authorization provided that the U.S. government is notified about the
+Internet location of the software.
+
+The open source software available on this web site is publicly
+available without license fee or royalty payment, and all binary
+software is compiled from the source code. The U.S. government has
+been notified about this site and the location site for the source
+code. Therefore, the source code and compiled object code may be
+downloaded and exported under U.S. export license exception (without a
+U.S. export license) in accordance with the further restrictions
+outlined above regarding embargoed countries, restricted persons and
+restricted end uses.
+
+Local Country Import Requirements. The software you are about to
+download contains cryptography technology. Some countries regulate the
+import, use and/or export of certain products with cryptography. The
+X.org Foundation makes no claims as to the applicability of local
+country import, use and/or export regulations in relation to the
+download of this product. If you are located outside the U.S. and
+Canada you are advised to consult your local country regulations to
