If you want to use a wikit to add a help facility to your scripted documents, there are a few steps that will make it a relatively simple exercise.
Firstly, add the following two lines to your bin/main.tcl startup script
add the following two lines to your '''bin/main.tcl''' startup script set topdir [file dirname [file dirname [info script]]] lappend auto_path [file join $topdir lib]
The first line saves the root directory of the scripted document - we'll use this later to locate the wiki help datafile. The second line makes sure the autoscroll, button and wikit packages can be found.
Next, create a subdirectory called doc and put your wiki datafile in there - for example lib/appname.tkd, where appname is the name of your application.
Then, you can display the wiki using the following commands, either from a menu or in your application startup script
package require Wikit Wikit::init [file join $topdir doc appname.tkd]
Note that the wiki will automatically be read-only, since a wiki file stored in a scripted document cannot be modified.
To update your wiki datafile, unpack the scripted document using sdx, edit it using wikit, then rebuild the scripted document, thus
sdx sd2fs appname.bin wikit appname.vfs/doc/appname.tkd sdx fs2sd appname
