## Summary:

  This package tries to re-implement some of nadvice.el's functionality
  on top of the old defadvice system, to help users of defadvice
  move to the new advice system without dropping support for Emacs<24.4.

  Limitations;
  - only supports `advice-add', `advice-remove', and `advice-member-p'.
  - only handles the :before, :after, :override, and :around kinds of advice;
  - requires a named rather than anonymous function;
  - and does not support any additional properties like `name' or `depth'.

## Recent NEWS:

Since 0.3:
- Fix a bug when advising functions that do not take arguments.
