wip/ruby-github-markup 4.0.2 NetBSD

This library is the first step of a journey that every markup file in a repository goes on before it is rendered on GitHub.com:

1. github-markup selects an underlying library to convert the raw
   markup to HTML. See the list of supported markup formats below.
2. The HTML is sanitized, aggressively removing things that could
   harm you and your kin-such as script tags, inline-styles, and
   class or id attributes.
3. Syntax highlighting is performed on code blocks. See
   github/linguist for more information about syntax highlighting.
4. The HTML is passed through other filters that add special
   sauce, such as emoji, task lists, named anchors, CDN caching
   for images, and autolinking.
5. The resulting HTML is rendered on GitHub.com.

Please note that only the first step is covered by this gem - the rest happens on GitHub.com. In particular, markup itself does no sanitization of the resulting HTML, as it expects that to be covered by whatever pipeline is consuming the HTML.
