Helpers to load and use recursive Gruntfiles.

module.exports = (grunt)->
    ###
     grunt.Config behaves almost exactly like grunt.initConfig(), except:
     Targets in multitasks are merged
     If a Gruntfile loaded later defines the same multitask target, the
     target is overwritten.
    ###
    grunt.Config =
        version: 'v1'
        testMulti:
            base:
                foo: 'bar'
        copy:
            test:
                files:
                    'src/test/copy/b': ['src/test/copy/a']

    ###
     The equal operator is overloaded to be array concatenation. The
     right hand side can be either a string or array of strings.
     Note, however, that all `grunt-*` tasks in node_modues will be
     loaded by grunt-recurse automatically.
