Does this module depend on Commerce Product Attributes or Commerce Product Pricing?

Bit confused here so bear with me...

On the module's homepage, step 2 of the instructions says:

"Install required modules Commerce Product Option and Commerce Product Attributes."

Where "Commerce Product Attributes" links to the commerce_product_attributes module.

But the module's .info file lists a dependency on Commerce Product Pricing:

dependencies[] = commerce_product_pricing

... and makes no mention of commerce_product_attributes.

So, which is right? :)

Thanks,

Alex
