Instructions on how to build the 2013 pre-release version of spot-on are in Documentation/COMPILING
There is also a file there called RELEASE-NOTES, where the version is described as 0.01, not 0.1 as the purported press-release did.
The release notes are short and to the point: "Version 0.01 of Spot-On is now available."
There is also a TO-DO file under Documentation which shows the parts of the software being developed by the author.
