Where:

<target>	Target architecture for cross-toolchain; examples (non exhaustive list): cortexa7hf-neon-vfpv4
<distro>	Distribution; examples (non-exhaustive list): openstlinux_weston
<host machine>	Host machine on which the SDK is installed; examples (non-exhaustive list): x86_64 (64-bit host machine)

The installed SDK consists of:

an environment setup script for the SDK
a configuration file for the target
a version file for the target
the root file systems (sysroots) needed to develop objects for the target system
