Reference a static variable in function docs

Hi all,

Earlier I found a resource that mentioned you can reference a static variable in function documents, but I’m unable to find the resource again to see how they did it.

How do you do it?

I’ve tried the following without success:

@doc """
  Starts up the ets table (with name @cache_name)
  yada yada yada
  """

and

@doc """
  Starts up the ets table (with name #{@cache_name})
  yada yada yada
"""
