<major>.<minor>.<revision>([ {{<qualifier>-<qualififer> ] | [ -<build> ])}}
where:
- the qualifier section is optional (and is SNAPSHOT, alpha-1, alpha-2)
- the build section is optional (and increments starting at 1 if specified)
- any '0' build or revision elements can be omitted.
- only one of build and qualifier can be given (note that the timestamped qualifier includes a build number, but this is not the same)
- the build number is for those that repackage the original artifact (eg, as is often done with rpms)
