The offical manual of PSX. Note at the momment the manual is not very attractive because most time is spent at coding. If we have some time we will try to update the manual content- and designswise. If you like to help feel free to contact me. The manual is written in XML following the DocBook schema. We use Saxon to transform the XML into HTML. You can see the XML at the repository.
The example page offers a growing number of PSX applications wich are documented and where you can see the source code. It is a great start to learn how PSX works.
