Can you discuss some of the differences between a product manual and a white paper?

"There are significant differences between a product manual and a white paper. A product manual is a detailed description of the product, with instructions on its use and how to resolve common issues. A white paper talks about a more general topic about the industry, technology, or solution related to the product. The purpose of a white paper is to provide useful information while promoting the organization's technology or products. It is meant to generate interest and lead to engagements between customers and the organization. A white paper is a sales tool while the product manual is a support tool."
