-# We have a conf and classes directory, prepend to BBPATH to prefer our versions

+# variable in toplevel bblayers.conf file, where bitbake will search
+# for .inc files and others where bitbake uses BBPATH since it will
+# search the directories from first to last as specified in BBPATH
+# Therefore if you want a given layer to be considered high priority
+# for the .inc and .conf etc. then consider it adding at the beginning
+# of BBPATH. For bblayers bitbake will use BBFILES_PRIORITY to resolve
+# the recipe contention so the order of directories in BBFILES does
+# not matter.

# We have a recipes directory, add to BBFILES
