DocBook files are validated, parsed and translated various presentation file formats using a combination of applications collectively called a DocBook tool chain. The function of a tool chain is to read the DocBook markup (produced by AsciiDoc) and transform it to a presentation format (for example HTML, PDF, HTML Help, EPUB, DVI, PostScript, LaTeX).

A wide range of user output format requirements coupled with a choice of available tools and stylesheets results in many valid tool chain combinations.
