"""Updates the python binaries that we cache store at
|
|
http://storage.google.com/webassembly.
|
|
|
|
Currently this is windows only and we rely on the system python on other
|
|
platforms.
|
|
|
|
We currently bundle a version of python for windows use the following
|
|
recipe:
|
|
1. Download the "embeddable zip file" version of python from python.org
|
|
2. Remove .pth file to work around https://bugs.python.org/issue34841
|
|
3. Download and install pywin32 in the `site-packages` directory
|
|
4. Re-zip and upload to storage.google.com
