HELP = <<-help
Usage: gfm [--readme | --plaintext] [<file>]
Convert a GitHub-Flavored Markdown file to HTML and write to standard output.
With no <file> or when <file> is '-', read Markdown source text from standard input.
With `--readme`, the files are parsed like README.md files in GitHub.com. By default,
the files are parsed with all the GFM extensions.
