// IMPORTANT(allen):
//  If Asset_Node or Asset_Manifest are edited at all it will invalidate
// all CDmanifest files.
//
//  If Asset_Flag or Asset_Type are rearranged it will invalidate all
// CDmanifest files.
//
//  If we _have_ to invalidate CDmanifest files we will have to write a
// one time convert which is time consuming, so usually finding a method
// other that does not invalidate our data format will be best.
//
//  If this turns into a big issue, I'll look into making a way to write
// these one time converts more quickly or to support a more flexible
// data format.
//
//  Note we can insert enumeration values in Asset_Type right above
// AssetType_TypeCount safely, as that value is just meant to count how many
// asset types we have and should not actually be stored in CDmanifest.
