Tengo script based rules

[aireilly]

Tengo opens a lot of possibilities, for example:

• Validate YAML in codeblocks (?)
• Check that code blocks are closed
• Include ‘$’ at beginning of [source,terminal] code snippets (#, sh4.4#, etc)
• Check for hardcoded version numbers in code blocks with a variable
• Ensure that every file has an abstract that is minimum 2 sentences long.
• The :_content-type: variable must be located before the file ID to avoid build problems.
• Flag missing anchor IDs for headings
• validate tables
