Below are the contents of a poster session I presented at the 1997 Tcl/Tk Workshop in Boston.
The short form of this presentation is that there are coding conventions peculiar to Tcl/Tk that can be used to make a Tcl/Tk program more adaptable to the environment it lives in, and in the process, reduce the number of changes that need to be made to the program when the functionality is extended.
These posters describe some of the conventions I've developed or stolen in the past few years. If you have an idea or two of your own, I'd be thrilled to hear about them, I'll add them to the list of conventions, and probably start using them myself.
