New Task to use node build script on existing non-node build script projects

[nimbupani]

I have an existing h5bp project I want to use node build script on. Right now the only way it is possible is to create a temporary new project and copy grunt.js and package.json back to the existing project.

We should have a way to do this by just copying over grunt.js and package.json (and perhaps have people fill in what is the css, img, js folder).

This is an interesting feedback. It's probably tricky to get this done right, we can think of a special grunt init template for this (with a bunch of prompt to fill in the Gruntfile configuration)

Or just copy over a Gruntfile and a package.json with extensive inline comments.

we're hitting this issue on Yeoman too.

Divya do you think a somewhat generic app config file (in json/yaml) that
is read by grunt/etc would make sense?

The most important thing is file paths, but then concatenation
rules/destinations are also pretty configurable.

I dont think another config file would help. I do not think we need a thorough check. Just verify that the essential comments for splitting css/html files exist. If they do not, find the main.css file and script files and wrap them with these html comments.

Then add a package.json and a grunt.js file. I am not sure if any additional changes are required.

If any folder is missing, we should output what folders are missing but not throw an error.
