+The layerindexlib module is designed to permit programs to work directly
+with layer index information.  (See layers.openembedded.org...)
+
+The layerindexlib module includes a plugin interface that is used to extend
+the basic functionality.  There are two primary plugins available: restapi
+and cooker.
+
+The restapi plugin works with a web based REST Api compatible with the
+layerindex-web project, as well as the ability to store and retried a
+the information for one or more files on the disk.
+
+The cooker plugin works by reading the information from the current build
+project and processing it as if it were a layer index.
+
+
+TODO:
+
+__init__.py:
+Implement local on-disk caching (using the rest api store/load)
+Implement layer index style query operations on a combined index
+
+common.py:
+Stop network access if BB_NO_NETWORK or allowed hosts is restricted
+
+cooker.py:
+Cooker - Implement recipe parsing
+

+This test data is used to verify the 'cooker' module of the layerindex.
+
+The module consists of a faux project bblayers.conf with four layers defined.
+
+layer1 - openembedded-core
+layer2 - networking-layer
+layer3 - meta-python
+layer4 - openembedded-layer (meta-oe)
+
+Since we do not have a fully populated cooker, we use this to test the
+basic index generation, and not any deep recipe based contents.
