+"""Wrapper script to fix aiohttp certificate validation.
+
+PyInstaller bundles OpenSSL with hangups. The path that OpenSSL searches for CA
+certificates is set at compile time, so to make hangups portable between Linux
+distributions we need to use the SSL_CERT_FILE or SSL_CERT_PATH environment
+variables to override it.
+
+Set SSL_CERT_FILE to the CA certificates bundled by requests. This allows
+aiohttp to validate certificates.
