Build tool for JavaScript

My own attempt at creating a build tool for linking with source files (after recursively building them, if needed).

In it's present state, it only creates symlinks to files pointed at in a 'build.json' file.

Format of a build.json file:

{
  "targetname": {
    "srcs": [...],
    "deps": [...],
    "to": {
      "dir": "...",
      "copy": true|false
    }
  },
  "othertarget": {...}
}

Example of a build.json file

{
  "test": {
    "srcs": ["test.js"],
    "deps": ["//javascript/namespace:namespace.js",
             "//javascript/array+clean:array+clean.js",
             "//javascript/date/build:date.js"],
    "to": {
      "dir": "./lib",
      "copy": false
    }
  }
}

Run using $ build test

Improvements

This is just the very first try. It can be massively improved for things like compiling sources, recursively building dependencies, integrating with other build tools like jake (which I hope will be possible).

Why do this?

Over the past four years, I have installed so many different libraries that after reorganizing all this source code along with libs I made myself, I needed a way to be able to load in any of these libraries whenever I want.
