The GLIBs provides functionality for the creation and manipulation of application configuration files. This task is already pretty easy to implement using Tcl list and dictionary functionality and hitherto I've used it all the time. But, having seen how useful this functionality is, I thought that it was time to implement the bindings. The way in which this is achieved is to treat such lists as objects so that multiple files can be opened for an application. This will allow the use of such lists to be more than simply an application config file. One of my pet apps is the scanning and creation of djvu ebooks. Sometimes the settings for a particular page need to be modified in order to get a good scan. Creating a config page for to control the page creation operation would be the better than an a 'one setting fits all' approach.
