.rst File — reStructuredText

reStructuredText (rST) is a lightweight markup language that is part of the Python Docutils project. Created by David Goodger in 2001, rST is the standard documentation format for Python projects and is the markup language used by the Sphinx documentation generator. rST provides richer semantic markup than Markdown, with support for footnotes, citations, tables, cross-references, automatic table of contents generation, and extensible directives and roles. The syntax uses underlined headings, indentation-based structure, and inline markup with special characters. rST is particularly powerful for large documentation projects because of its ability to split content across multiple files, create sophisticated cross-reference systems, and output to multiple formats including HTML, PDF, LaTeX, EPUB, and man pages. While more complex than Markdown, rST offers features essential for comprehensive technical documentation, including domain-specific markup for documenting APIs, configuration options, and command-line interfaces.
