Happy (nuget): Happy has JavaScript-like syntax and and includes a special template syntax which can be used to enable your best tendencies for being "effienctly lazy."  With Happy, it's easy to write a generator for any kind of text based output including HTML, XML, CSS, Javascript, C#, VB.Net, SQL, YAML, Java, Markdown, etc, etc. If it's text-based you can write a program in Happy to generate it.  It's also based on the DLR, so you can consume any .Net type and easly interact with it using any .Net language supporting dynamic types (C#, VB.Net, F#, IronRuby, IronPython, etc). This package includes the script engine library.
