      6 # to "build" .isolate files into a .isolated file.
      7 #
      8 # To use this, create a gyp target with the following form:
      9 # 'conditions': [
     10 #   ['test_isolation_mode != "noop"', {
     11 #     'targets': [

     27 #   }],
     28 # ],
     29 #
     30 # Note: foo_test.isolate is included and a source file. It is an inherent
     31 # property of the .isolate format. This permits to define GYP variables but is
     32 # a stricter format than GYP so isolate.py can read it.
     33 #
     34 # The generated .isolated file will be:
     35 #   <(PRODUCT_DIR)/foo_test.isolated
     36 #
