The constant SDLVersionInfo is defined for each unit of the SDL Component Suite. It references the version string which consists of three parts separated by underscore ('_') characters:
unitname_versionnum_editionThe 'unitname' part contains the name of the unit (all lowercase letters), the 'versionnum' part contains the version number in form of a three digit string. The first digit is the main release number, the second and third digit represent the secondary release. Finally, the 'edition' part contains either the substring 'full' for the registered (paid) version, or 'lighted' for the free Light Edition.
