+#
+# Enables the root account on a Rackspace cloud database instance.
+#
+# Usage:
+#
+#   enable-rs-db-root name.of.your.instance.example.com
+#
+# Rackspace cloud databases disable the root account by default, meaning
+# that you have to create databases etc. through the GUI or over the API
+# rather than through standard mySQL tools. The root account can't be
+# enabled through the GUI, but it can be enabled over the API; this
+# script does that.
+#
+# Requires Ruby and the fog gem (`gem install fog`).
+#
+# Assumes your Rackspace credentials are in environment variables called
+# `RACKSPACE_USERNAME` and `RACKSPACE_API_KEY`.
