[describe what the word framework means]
To some, framework is another term for library, or class, or set of functional code designed for one to build upon.
In general, the term 'framework' is generally thought of as an infrastructure layer. Using it makes doing some specific type of development easier.
In tcl, an extension designed to streamline the building of a megawidget might be called a framework.
[ DKF: I note here that "Framework" means something specific in relation to MacOS X, but don't understand exactly what it is. Can someone expand on this? ] LV Well, read http://developer.apple.com/documentation/MacOSX/Conceptual/SystemOverview/Bundles/chapter_5_section_1.html
and then
http://developer.apple.com/documentation/MacOSX/Conceptual/SystemOverview/Frameworks/chapter_7_section_1.html is a part of the Mac OS X documentation
and perhaps that will help a bit.
RS finds that Tcl/Tk themselves make a great framework. Earlier, I crafted my own convenience routines in Tcl, leading to package dependencies and less readable code... So I changed to using pure-Tcl as far as possible (and that's very far!)
