The name "Wikit" can be interpreted in two ways:
Both are accurate.
Wikit can be used as a CGI process (see Wikit under CGI), in which case it becomes a part of your web server, or it can be used standalone, running locally with a Tcl/Tk graphical front end (see Wikit in local mode). The former makes collaborative editing possible, the latter includes a high-performance search facility and makes it very easy to browse and edit information off-line.
Right now, these two mechanisms do not mix.
What you can do, however, is download a copy of an active web-based WiKit (such as this one, the Tcl'ers Wiki), and keep it around as reference to what that snapshot contains. WiKit is fully self contained in a single platform-independent file, called a Starkit. It requires a platform-dependent runtime called Tclkit, There are runtimes for over a dozen platforms.
As of 2002, Wikit can be embedded as a hyperlinked and searchable help system.
