+This directory contains pre-compiled extensions modules used to test completions
+for compiled modules on Travis-CI (Ubuntu 12.04 64bit).
+
+To build the extensions modules, run::
+
+    python setup.py build_ext -i
+
+
+Then move the compiled modules to their testing package ( ./**compiledXX**, where XX is the
+python version used to run setup.py).
