# This file is meant to be included into a target to provide a rule
# to "build" .isolate files into a .isolated file.
#
# To use this, create a gyp target with the following form:
# 'conditions': [
#   ['test_isolation_mode != "noop"', {
#     'targets': [
#       {
#         'target_name': 'foo_test_run',
#         'type': 'none',
#         'dependencies': [
#           'foo_test',
#         ],
#         'includes': [
#           '../build/isolate.gypi',
#         ],
#         'sources': [
#           'foo_test.isolate',
#         ],
#       },
#     ],
#   }],
# ],
#
# Note: foo_test.isolate is included and a source file. It is an inherent
# property of the .isolate format. This permits to define GYP variables but is
# a stricter format than GYP so isolate.py can read it.
#
# The generated .isolated file will be:
#   <(PRODUCT_DIR)/foo_test.isolated
#
# See http://dev.chromium.org/developers/testing/isolated-testing/for-swes
# for more information.
