WHAT IS semver.info.count ??

Hello! If find nowhere in the documentation, what is the purpose and value of "semver.info.count"

`formatter = { "${semver.info.version.major}.${semver.info.version.minor}.${semver.info.version.patch}+build.${semver.info.count}.sha.${semver.info.shortCommit}" } // (default) version formatting closure
`

Could you please shed some light and/or add it to the documenation??
