Eric Sink is the founder of SourceGear, a software vendor in central Illinois. In 2003, SourceGear released Vault, a version control tool designed to be a replacement for SourceSafe. Nine years later, Vault continues to be a successful product in its niche. More recently, Eric has been focused on a next-generation project. Veracity is a Distributed Version Control System (like Git and Mercurial). It is open source (Apache License) and cross-platform (Windows, Mac, Linux). In 2011, Eric published a free book called Version Control by Example. VCBE is available online and free printed copies are available from SourceGear (until we run out).
