1. Make a package called `static-html` that just compiles `<head>` and `<body>` tags inside `.html` files. Much like templating but without the templates.
2. Refactor `templating` to avoid duplicating code.
Split out code that would be shared between `templating` and `static-html` into a new `templating-tools` package. These tools could also be used to simplify implementation of other build plugins, like `simple:markdown-templating`.
This also has the added benefit of moving as much code as humanly possible out of the `templating` package, so that it can be reused in other packages.
1. `templating-tools` package and its README
2. `static-html` package and its README
3. `caching-html-compiler` is not new code; it is just code factored out of the batch plugin version of `templating`, but the README and some comments are new.
1. `tools/tests/static-html.js` tests static html and error handling
2. `templating-tools/html-scanner-tests.js` tests `scanHtmlForTags` and `compileTagsWithSpacebars` together.
All unit tests pass on this branch.
