I found dub.json has very important info, To name three : importPaths , libs , dependencies. When these are right you have started for 80%.Without nagging, when you begin you are however lost in the woods and it makes the impression to lose interest completely.
For ease there is : targetName, targetPath, sourcePaths.
What is also quite annoying is links to libraries which are unmaintained. E.g. sql-libraries where no code check-in has been done for almost ten years.
