Usage:
    $cmd [--flavor=<flavor>] [--full] [file.md]

    --flavor  specifies the markdown flavor to use. If omitted the original markdown by John Gruber [1] will be used.
              Available flavors:

              gfm - Github flavored markdown [2]
              extra - Markdown Extra [3]

    --link-style  specifies how links are being rendered:

              footnote (default) - render all links with a footnote, which contains the full URL of the link. This is good for printing the PDF.
              href - render all links with a hyperref, similar to HTML, the link target is not visible in this case.

    --full    ouput a full TEX document with document class, begin and end document. If not given, only the parsed markdown will be output.

    --help    shows this usage information.

    If no file is specified input will be read from STDIN.

Examples:

    Render a file with original markdown:

        $cmd README.md > README.tex

    Render a file using gihtub flavored markdown:

        $cmd --flavor=gfm README.md > README.tex

    Convert the original markdown description to html using STDIN:

        curl http://daringfireball.net/projects/markdown/syntax.text | $cmd > md.tex
