1"""A helper module that injects SecureTransport, on import. 

2 

3The import should be done as early as possible, to ensure all requests and 

4sessions (or whatever) are created after injecting SecureTransport. 

5 

6Note that we only do the injection on macOS, when the linked OpenSSL is too 

7old to handle TLSv1.2.
