Journal paper on abc
Transactions on Aspect-Oriented Software Development (TAOSD) is a new journal dealing with AOP and related fields. Its first issue will contain an article on extending abc, which will be the most thorough account of the process yet.
The paper is titled "abc: An extensible AspectJ compiler", and is an expanded and updated version of our AOSD'05 paper . It is available online from the AspectBench web page and should be the perfect place to start reading if you're thinking of extending abc.
