# Zulip's OpenAPI-based API documentation system is documented at
#   https://zulip.readthedocs.io/en/latest/documentation/api.html
#
# This file defines the Python code examples that appears in Zulip's
# REST API documentation, and also contains a system for running the
# example code as part of the `tools/test-api` test suite.
#
# The actual documentation appears within these blocks:
#   # {code_example|start}
#   Code here
#   # {code_example|end}
#
# Whereas the surrounding code is test setup logic.
