Better to generate the dividing core and npm?

[kazuhisya]

Node.js and npm was distributed separately before. However, came to be bundled from node.js 0.6.3 before and after.
Since then, I changed it to generate, including the npm to rpm of node.js.
but began to think better to divide it normally is or not good.

For example, it will be added as follows in spec file.

%package npm
