Description: Toolchain definitions and utilities for Linux

This module provides toolchain definitions and utilities for targeting Linux.
See "Development.Shake.Language.C.Rules" for examples of how to use a target
toolchain.

Linux is also a supported host operating system, see
"Development.Shake.Language.C.Host" for examples of how to target the host.
