How to create a custom attribute ?

Hello, i want to know how to create custom attributes like this:

#[my_attribute()]
struct Something {
...
}

Could you help me ?

Since proc macros have recently been stabilized it seems that the guide I wrote for them in the Unstable Book has disappeared, and now we don't really have any public documentation for them. That's unfortunate.

@steveklabnik should we just move the old Unstable Book entry for the proc_macro feature to TRPL or something?

I’ll be writing the chapter this week.
