This change adds an option which allows users to specify
the number of version components (i.e. values between dots)
The default behavior is preserved, and is equivalent to using
'-1' as the value.
- Negative values remove items from the end.
- Positive values specify the count of of components
- Zero will remove the version field entirely from the symlink
- When nonzero, at least one version component will appear
