Package naming 1 Runtime package and design package: The runtime package should only contain the required units. The units for the property editor and component editor should be placed in the design-time package. Registration units should also be included in the design phase package. 2 File naming standards: The naming of packages follows two modes: iiiLibvv.pkg - design-time package and iiiStdvv.pkg - run-time package. (Note that lib or std in the package name indicates whether this is a design-time package or a run-time package.) iii represents a 3-character prefix used to identify a company, individual, or other things that need to be identified. vv represents the version number of the package, which also includes the Delphi version number. For example: the packages in this book are named like this: lxLib70.pkg - design package lxStd70.pkg - runtime package
