Information about package

Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library. In contrast to most existing tools for converting Markdown to HTML, pandoc has a modular design: it consists of a set of readers, which parse text in a given format and produce a native representation of the document, and a set of writers, which convert this native representation into a target format. Thus, adding an input or output format requires only adding a reader or writer. For pdf output please also install pandoc-pdf.
