- * \brief Representation of a version.
- *
- * K3bVersion represents a version consisting of a major version (accessible via majorVersion()),
- * a minor version (accessible via minorVersion()), a patchLevel (accessible via patchLevel()),
- * and a suffix (accessible via suffix()).
- *
- * The major version is mandatory while all other fields are optional (in case of the minor version
- * and the patchlevel -1 means that the field is undefined).
- *
- * K3bVersion tries to treat version suffixes in an "intelligent" way to properly compare versions
- * (see compareSuffix() for more details).
- *
- * K3bVersion may also be used everywhere a QString is needed as it automatically converts to a
- * string representation using createVersionString().
