+``cfwatch`` |pypi|
+==================
+
+Automagically purges CloudFlare's cache when local files are updated.
+
+This is useful for exporting a directory of files via CloudFlare. If
+your files are updated, ``cfwatch`` will automatically purge the
+corresponding URL on CloudFlare.
+
+With ``cfwatch``, you will no longer need to add cache busting query
+strings, and the direct link will always work.
+
+Usage

+
+  $ pip install cfwatch
+  $ cfwatch --help
