+
+    <p>
+      The libvirt repository makes use of a large number of programming
+      languages. It is anticipated that in the future libvirt will adopt
+      use of other new languages. To reduce the overall burden on developers,
+      there is thus a general desire to phase out usage of some of the
+      existing languages.
+    </p>
+
+    <p>
+      The preferred languages at this time are:
+    </p>
+
+    <ul>
+      <li>C - for the main libvirt codebase. Dialect supported by
+        GCC/CLang only.</li>
+      <li>Python - for supporting build scripts / tools. Code must
+        run with both version 2.7 and 3.x at this time.</li>
+    </ul>
+
+    <p>
+      Languages that should not be used for any new contributions:
+    </p>
+
+    <ul>
+      <li>Perl - build scripts must be written in Python instead.</li>
+      <li>Shell - build scripts must be written in Python instead.</li>
+    </ul>
