JSDoc for methods with multiple signatures

First I've thought about union types but they can solve only part of the problem. Original discussion started here. In case codeplex had been abandoned, I copy my question here.

Please take a look at this function. https://github.com/digitalbazaar/forge/blob/master/js/rsa.js#L802-L885 As you can see from comments there are a lot of ways to use it. If I need to make a type definitions for it (actually I do) with JSDoc Intellisense support, then I have to copy general function description like 10 times. This will make my definition 3 times longer than source function and also very hard to modify. In libraries like forge almost all functions have being made that way.

Can you give me some tip about making definitions in such circumstances?

まず、js/rsa.js#L802-L885 にあるリンク先の forge の例と、コピーされた CodePlex の議論を読んでください。issue では TypeScript ファイル、テスト、合意済みの動作のいずれも特定されていません。実装作業を特定する前に、望ましい JSDoc の表現と受け入れ基準を確立してください。
