On Chao Y's webpage for the IPP Integration Wrappers, section 2.1 says:
"Getting Started instructions are provided in the Integration Wrappers Developer Guide and Reference. You can find this document the following folder available after you install the Intel® IPP Integration Wrappers Preview package: /interfaces/integration_wrappers."
However, this does not appear to be the case, at least for the Linux or Mac packages. The Developer Guide and Reference is actually missing from these packages.
