How to load AMD modules when using Angular JS?

For some strange reason, Angular JS has its own modular system, which is neither AMD nor CommonJS .

I have many existing modules in AMD format. I would like to use them in an Angular app.

I would not want to rewrite any AMD modules. If possible, I would also like to avoid using Angular's own modular system.

Can i use AMD modules when using Angular? Is it possible to avoid using the Angular custom module system?
