-# NOTE: THIS FILE IS DEPRECATED. Please add new entries to the recipes themselves.
-#
-# upstream_tracking.inc - This file contains data that tracks the
-# upstream project associated with a given recipe. This list is needed
-# for recipes that version information can not be automagically discovered.
-# As we automate this checking, this file will slowed be reduced.
-#
-# This data is used by the package reporting system (packages.yoctoproject.org)
-#
-# The format is as a bitbake variable override for each recipe
-#
-#       RECIPE_UPSTREAM_VERSION_pn-<recipe name> = "<version>"
-#       RECIPE_UPSTREAM_DATE_pn-<recipe name> = "Mmm dd, YYYY"
-#	 - This is the latest upstream version and date
-#       RECIPE_NO_UPDATE_REASON_pn-<recipe name> = "<free form text>"
-#        - Used to note why a recipe should not be upgraded to a newer versoin
-#       CHECK_DATE_pn-<recipe name> = "Mmm dd, YYYY"
-#        - This is the date that upstream was last manually checked over time
-#          this should be removed as we automate this checking
-#
-# These entries will slowly be removed as we can automatically determine
-# the information in this file.  So for existing recipes that we can get 
-# from the Recipe reporting system, the entries here can be removed.
