phpGroupWare is a multi-user web-based suite written in PHP. It contains many applications, including a Calendar, email package, contact database and project manager. It also includes an extensive API for writing new applications. Brandon Neill just wanted to figure out how to use the program and decided to write a manual as an excuse to bug the developers. I would like to thank the many authors of phpGroupWare and it's applications for creating such a useful and extensible product. I would also like to thank the authors of previous version of the documentation and the authors of the LDP Author guide for teaching me how to use DocBook. This document is based upon the current CVS release, where possible I included notes relating to the current stable release (0.9.12). This is a work in progress, please email any corrections to bneill@yahoo.com.
