Third-party software components that are distributed with MultiTouch Cornerstone are described below.

The main use, license and the web site for obtaining further information is listed below for each component. The license details can be found from the relevant web sites.

Libraries

Libraries are software components that are linked into Cornerstone applications. The licenses of the used libraries have been reviewed to be compatible with proprietary software development.

Part of the libraries are used in a prominent way and they are part of the Cornerstone API (for example Qt). Others, like PortAudio, are hidden from the end-users and are used only internally in some Cornerstone components.
