install

public static DeltaBuilder install(Version version,
                                   String description)

startup

public static DeltaBuilder startup(ModuleDefinition moduleDef,
                                   List<Task> tasks)

checkPrecondition

public static DeltaBuilder checkPrecondition(String minimalVersion,
