Rating : - Informative but not always detailed enough
I manage a TWiki installation for a large media company and bought this book when I was first hired to get myself more familiar with the system. At first it wasn't very useful because it looks at very specific uses of TWiki. However, as I've begun to work with the system and create my own applications, it has been a very handy supplement to the somewhat skimpy documentation in TWiki itself. For example, the section on Search Strings revealed its value only at the point where I needed to learn more about regular expressions in order to create more complex content management tools. I also have found the included tools and full installation of TWiki to be of great use in providing me with a TWiki sandbox for experimentation. However, as someone with an extensive background in techncial writing, I sometimes find the information provided to be lacking in enough detail; the section on skins and templates, for example, is useful for describing the mechanics of FreeSkin and FlexibleSkin, but doesn't provide enough information on how to use or modify these skins, or the complexities of managing templates. If you are a TWiki admin, or someone interested in creating TWiki applications, I would recommend this as a useful supplement to the documenation included with TWiki.
