#
# This script runs the full set of tests for product config:
# 1. Build the product-config tool.
# 2. Run the unit tests.
# 3. Run the product config for every product available in the current
#    source tree, for each of user, userdebug and eng.
#       - To restrict which products or variants are run, set the
#         PRODUCTS or VARIANTS environment variables.
#       - Products for which the make based product config fails are
#         skipped.
#

# The PRODUCTS variable is used by the build, and setting it in the environment
# interferes with that, so unset it.  (That should probably be fixed)
