/** \class cmPackageInfoArguments
 * \brief Convey information about a package.
 *
 * This class encapsulates several attributes of package metadata. It is used
 * both as a convenience container to convey several values in a single
 * container, and also provides utilities to obtain this metadata from commands
 * which produce packages (i.e. export and install).
