## Overview

tldr-python-client is a command-line client for looking up tldr command pages. The principal workflow parses CLI options, selects platform and language, obtains a page from a remote source or local cache, and renders it to the terminal. The single substantial runtime file also provides cache maintenance, command listing, search, and local Markdown rendering. The source excerpt is partial, so links for some documented capabilities are left unverified rather than inferred.

Main entry points: [`tldr.py`](https://github.com/tldr-pages/tldr-python-client/blob/main/tldr.py) (CLI entry)
