Comet allows you to easily insert a comment block for commenting on code. Developers will be required to document code written by themselves often. A large project has many classes and categories, properties, and methods. You need to add comments to all of them when you generate to a document, which will take a long time. Comet will take it on a part of heavy work. It will not be able to write comments, but add comment block formatted for appledoc to places that needs. This will prevent omissions.
