The agent can list or download snapshots, constrain by date, deduplicate archives, and preserve evidence locally before a site changes or disappears.\n\n## Prerequisites\n\nPython 3, pip, a target URL, local disk space for archived snapshots, and optional tqdm for progress output.\n\n## Installation\n\nUse the upstream install or setup path that matches your environment:\n- pip install waybackpack\n\nRequirements and caveats from upstream:\n- [![Version](https://img.shields.io/pypi/v/waybackpack.svg)](https://pypi.python.org/pypi/waybackpack) [![Support Python versions](https://img.shields.io/pypi/pyversions/waybackpack.svg)](https://pypi.python.org/pypi/w...\n- Requires tqdm to be installed.\n- Waypackback is written in pure Python, depends only on [requests](docs.python-requests.org), and should work wherever Python works. Requires Python 3.3+.\n\nBasic usage or getting-started notes:\n- For instance, to download every copy of the Department of Labor's homepage through 1996 (which happens to be the first year the site was archived), you'd run:\n- [--from-date FROM_DATE] [--to-date TO_DATE]\n- [--user-agent USER_AGENT] [--follow-redirects]\n\n- Source: https://github.com/jsvine/waybackpack\n- Extracted from upstream
