API:KSPModule
From Kerbal Space Program Wiki
KSPModule is an attribute with unknown use, possibly for classes extending PartModule. Seems unnecessary to use this.
// From Kerbal Space Program\KSP_Data\Managed\Assembly-CSharp.dll [AttributeUsage(AttributeTargets.Class, AllowMultiple = false)] public class KSPModule : Attribute { public string guiName; public KSPModule(string guiName); }
