Version is a Go library that provides version normalization and
 comparisons. It can also verify that a provided version string
 falls within a given range.
 .
 Examples:
   version.CompareSimple("1.2", "1.0.1")
   version.Compare("2.3.4", "v3.1.2", "<")
   .
   c := version.NewConstrainGroupFromString(">2.0,<=3.0")
   c.Match("2.5.0beta")
