+# This script runs tests defined in meta/lib/selftest/
+# It's purpose is to automate the testing of different bitbake tools.
+# To use it you just need to source your build environment setup script and

+# Call the script as: "oe-selftest" to run all the tests in in meta/lib/selftest/
+# Call the script as: "oe-selftest <module>.<Class>.<method>" to run just a single test
+# E.g: "oe-selftest bboutput.BitbakeLayers" will run just the BitbakeLayers class from meta/lib/selftest/bboutput.py
