The version string of a software package name is a maximum of 64 single-byte characters long and can be divided into tokens, using the dot character as the divider. Each token identifies a version or sub-version of the software package. For example, the software package name and version could be constructed as follows:

package_name.majorversion.minorversion.patchnumber

The three strings following the first dot provide versioning information about the package. They represent the following sequence in the development of the software package:

1. New features are added to the product. This is indicated by incrementing the first token.
2. The software is adapted to meet changes in hardware configurations, operating system versions, data formats, and so on. This is indicated by incrementing the second token.
3. Faults in the software are corrected. This is indicated by incrementing the third token.
