Constants

const AppName string = "goBlue/util"

AppName is the name of the application

const FullVersion string = AppName + VersionMajor + "." + VersionMinor + VersionBuild

FullVersion contains the full name and version of this package in a printable string

const VersionBuild string = "s"

VersionBuild is the type of this release. s(table), b(eta), d(evelopment), n(ightly)

const VersionMajor string = "0"
