-# This file is meant to be included into an action to copy test data files into
-# an iOS app bundle. To use this the following variables need to be defined:
-#   test_data_files: list: paths to test data files or directories
-#   test_data_prefix: string: a directory prefix that will be prepended to each
-#                             output path.  Generally, this should be the base
-#                             directory of the gypi file containing the unittest
-#                             target (e.g. "base" or "chrome").
-#
-# To use this, create a gyp target with the following form:
-# {
-#   'target_name': 'my_unittests',
-#   'conditions': [
-#     ['OS == "ios"', {
-#       'actions': [
-#         {
-#           'action_name': 'copy_test_data',
-#           'variables': {
-#             'test_data_files': [
-#               'path/to/datafile.txt',
-#               'path/to/data/directory/',
-#             ]
-#             'test_data_prefix' : 'prefix',
-#           },
-#           'includes': ['path/to/this/gypi/file'],
-#         },
-#       ],
