+
+Welcome to Glance's documentation!
+==================================
+
+The Glance project provides services for discovering, registering, and
+retrieving virtual machine images. Glance has a RESTful API that allows
+querying of VM image metadata as well as retrieval of the actual image.
+
+VM images made available through Glance can be stored in a variety of
+locations from simple filesystems to object-storage systems like the
+OpenStack Swift project.
+
+Glance, as with all OpenStack projects, is written with the following design
+guidelines in mind:
+
+* **Component based architecture**: Quickly add new behaviors
+* **Highly available**: Scale to very serious workloads
+* **Fault tolerant**: Isolated processes avoid cascading failures
+* **Recoverable**: Failures should be easy to diagnose, debug, and rectify
+* **Open standards**: Be a reference implementation for a community-driven api
+
+This documentation is generated by the Sphinx toolkit and lives in the source
+tree.  Additional documentation on Glance and other components of OpenStack can
+be found on the `OpenStack wiki`_.
+
+.. _`OpenStack wiki`: http://wiki.openstack.org

+JSON related utilities.
+
+This module provides a few things:
+
+    1) A handy function for getting an object down to something that can be
+    JSON serialized.  See to_primitive().
+
+    2) Wrappers around loads() and dumps().  The dumps() wrapper will
+    automatically use to_primitive() for you if needed.
+
+    3) This sets up anyjson to use the loads() and dumps() wrappers if anyjson
+    is available.
