text processing system for reStructuredText - documentation
reStructuredText is an easy-to-read, what-you-see-is-what-you-get plaintext markup syntax and parser system. It is useful for in-line program documentation (such as Python docstrings), for quickly creating simple web pages, and for standalone documents. . The purpose of the Docutils project is to create a set of tools for processing reStructuredText documentation into useful formats, such as HTML, LaTeX, ODT or Unix manpages. . This package includes documentation in HTML and (gzipped) reST formats.
