We need a tool/script that can update version number everywhere in the project by executing a single command. Following are the constraints,

1. We decide the version numbers manually.
2. We want to update to a new version number by executing a single command.
3. The way to do it should be simple - Say, some-tool 1.0.1-dev 1.0.1-alpha.
