+# Released under the MIT license (see COPYING.MIT)
+#
+# This bbclass is designed to extract data used by OE-Core during the build process,
+# for recording in the Toaster system.
+# The data access is synchronous, preserving the build data integrity across
+# different builds.
+#
+# The data is transferred through the event system, using the MetadataEvent objects.
+#
+# The model is to enable the datadump functions as postfuncs, and have the dump
+# executed after the real taskfunc has been executed. This prevents task signature changing
+# is toaster is enabled or not. Build performance is not affected if Toaster is not enabled.
+#
+# To enable, use INHERIT in local.conf:
+#
+# INHERIT += "toaster"
+#
