|
|
#
|
|
# Add files for macosx64 platform at the specified version:
|
|
# > python cef_json_builder_example.py add macosx64 3.2704.1416.g185cd6c 51.0.2704.47
|
|
#
|
|
# Add files for all platforms at the specified version:
|
|
# > python cef_json_builder_example.py add all 3.2704.1416.g185cd6c 51.0.2704.47
|
|
#
|
|
# See cef_json_builder.get_platforms() for the list of supported platforms.
