+Description: Pydantic OpenAPI schema implementation (Python module)
+ The OpenAPI Specification (OAS) defines a standard, language-agnostic interface
+ to HTTP APIs which allows both humans and computers to discover and understand
+ the capabilities of the service without access to source code, documentation,
+ or through network traffic inspection. When properly defined, a consumer can
+ understand and interact with the remote service with a minimal amount of
+ implementation logic.
+ .
+ An OpenAPI definition can then be used by documentation generation tools to
+ display the API, code generation tools to generate servers and clients in
+ various programming languages, testing tools, and many other use cases.
+ .
+ This package contains the OpenAPI schema implemented in Pydantic.
