This repository is the official Python Enhancement Proposals (PEP) infrastructure. It is a static site generator built on Sphinx that transforms PEP documents written in reStructuredText (RST) with RFC 2822 headers into the HTML website hosted at peps.python.org. The system includes custom Sphinx extensions for parsing PEP-specific metadata (headers, banners, references), generating indices (PEP 0, numerical, topical), and producing machine-readable outputs (JSON API, RSS feed, iCalendar). The build pipeline is orchestrated by a Makefile and build.py, with CI/CD via GitHub Actions that lint, test, and deploy to GitHub Pages with Fastly CDN purging. The repository also contains release management automation that reads python-releases.toml and updates release schedule PEPs programmatically. While primarily a documentation publishing system, it also serves as the canonical archive of Python language design decisions and packaging standards, with a read-only JSON API consumed by external tools.
