"""This module provides dynamic access to deprecated Zapier tools in LangChain.

It supports backward compatibility by forwarding references such as
`ZapierNLAListActions` and `ZapierNLARunAction` to their updated locations
in the `langchain_community.tools` package.

Developers using older import paths will continue to function, while LangChain
internally redirects access to the newer, supported module structure.
