Guide generation
Guide generation is phpDocumentor's implementation for converting hand-written documentation into a static page integrated with the API Documentation. These share each other's Table of Contents in order for them to link to one another.
The design for the Guide Generation is based on the premise that we could support multiple input formats (RestructuredText, Markdown, Textile, etc); but in the first version RestructuredText is the only supported input format.
Attribution
The code for rendering guides using RestructuredText-based documentation is based on, and with permission of, Ryan Weaver his work on the docs-builder package, combined with the RST-Parser by Doctrine (which is based off that of Gregwar).
