A couple of months ago I started working on a
Typo3 project for a client, and at about the same time I was asked by the folks at
Packt Publishing to review a book, so the choice fell naturally on "
Typo3 Extension Development" by Dmitry Dulepov.
The book, published in September 2008, covers the entire extension development life cycle, from planning to uploading it to the Typo3 Extension Repository (
TER).
