-`go-bumpver` takes the sequence of version(s) from a file or stdin and prints the next version. It drops invalid versions in the sequence and only uses valid ones. It does not make a tag or change any state in git or any other VCS it only prints the next version.

 ### Pre-release
 
 Pre-releases can be formatted in a way that can be easily bumped. Providing `--prerelease` will generate a new prerelease for the given bump. Meaning if you use `major --prerelease` with the last version 1.2.2 will give `2.0.0-RC.0`.
