SAPUI5 icon set

Hi,

I noticed SAP UI5 has a really nice extensive icon set:

https://sapui5.netweaver.ondemand.com/sdk/#test-resources/sap/m/demokit/icon-explorer/index.html#page|%7B%22id%22%3A%22Group%22%7D|0

I was just wondering if anyone knows if it is available to download and what the licence restrictions would be in using some of these icons in a native app which integrates with SAP.

Thanks,

Brad
