On the Ibuildings blog today Marcello Duarte has a new review of the Packt Publishing book "PHP5 CMS Framework Development" (by Martin Brampton).
Martin left Mambo (before they announced to drop support for PHP4 last September) to write his own CMS and "evolve out of the Mambo history", by taking advantage of PHP5 OO enhancements. The result is Aliro: a CMS, a framework and an extension project with traits and genes of the Mambo family. Aliro code is used throughout the book to support and illustrate his presentation.
Topics of the different chapters include basic CMS system needs, organizing code, extensions and editing and presenting content.
