Laurentiu Palcu - July 31, 2012, 8:49 a.m.
In order for the SDK to be relocatable, the user would need to call a
setup script to change the binaries acordingly. Having an auto-extracting
archive has the advantage of being more user friendly and the user does
not have to call the setup script separately after extracting the SDK.
It is called automatically.
