This directory contains the source code for the core of the Fuchsia SDK. The SDK itself is produced as an output of the build by processing the contents of this directory. For example, this directory might contain the source code for a library that is included in the SDK as a prebuilt shared library.
Software outside of the Fuchsia Source Tree should depend only on the Fuchsia SDK.
The API surface described by the SDK is governed by the Fuchsia API Council and should conform to the appropriate API rubrics.
