+# The following logging mechanisms are to be used in bash functions of recipes.
+# They are intended to map one to one in intention and output format with the
+# python recipe logging functions of a similar naming convention: bb.plain(),
+# bb.note(), etc.
+#
+# For the time being, all of these print only to the task logs. Future
+# enhancements may integrate these calls with the bitbake logging
+# infrastructure, allowing for printing to the console as appropriate. The
+# interface and intention statements reflect that future goal. Once it is
+# in place, no changes will be necessary to recipes using these logging
+# mechanisms.
+
+# Print the output exactly as it is passed in. Typically used for output of
+# tasks that should be seen on the console. Use sparingly.
+# Output: logs console
+# NOTE: console output is not currently implemented.
