	Introduction to the Tcl Programming Language
		Tcl is specially designed to make it extremely easy to extend the language by the addition of new primitives in C. These new primitives are truly first-class citizens of the language, sharing the same error handling and memory management as the original primitives.
		Tcl supports event-driven programming (required for GUI programming) with the ability to associate Tcl code with any variable or array element (the code is executed automatically whenever the variable is read or written).
		[incr tcl] is a pun on C++: "[incr tcl]" is the Tcl idiom for incrementing a variable.

	TIP #50: Bundle [incr Tcl] with the Core Tcl distribution (Site not responding. Last check: 2007-10-13)
		[incr Tcl] [1] shall be bundled with the core Tcl distribution.
		The location of the [incr Tcl] source tree shall be left to the discretion of the affected maintainers.
		Since an earler proposal (TIP #6) to incorporate [incr Tcl] into the Core failed to garner the necessary votes, at least in part because participants were uncertain of the rationales, it seems wise to discuss the individual points in further detail.

		Tcl can also be used for a variety of web-related tasks and for creating powerful command languages for applications.
		[incr Tcl] is an object-oriented extension of the Tcl language.
		The goal of this extension is to expose Tcl 8.4's new filesystem C API to the Tcl level.

	[No title]
		This is because the building blocks of vanilla Tcl are procedures and global variables, and all of these building blocks must reside in a single global namespace.
		Among other things, [incr Tcl] can be used to create new widgets that look and work like the usual Tk widgets, but are written entirely at the Tcl language level (C code is optional).
		For example, the current release of [incr Tcl] has a namespace "itcl" for object-oriented support, a namespace "itk" for mega-widget support, and a namespace "iwidgets" for the [incr Widgets] package.

	A Qualitative Analysis of the Usability of Three Contemporary Scripting Languages
		Tcl's [Incr Widget] (megawidgets) library was by far the hardest, thanks in part to the need to mix raw Tk widgets with [incr Tk] megawidgets.
		Tcl’s block delimiters were the worst: the need to use ‘\’ as line connectors, semicolons as line terminators, and # as comments accounted for most of these Tcl defects.
		Tcl's Array (Hash) construct is awkward to use from within [incr Tcl] classes.

	Objects in TCL (Site not responding. Last check: 2007-10-13)
		TCL does not offer object oriented primitives, but it is flexible enough to accomodate new primitives.
		But since TCL is a dynamic language, in which you can introduce new procedures and new variables at run-time, it seems more appropriate to also allow the creation of new methods and member variables at run-time.
		TCL allows us to create a procedure and an array variable with the same name, so we can call our object command 'a1' and use an array 'a1' to store the attributes of that object.

	incr Tcl
		[incr Tcl] (the humorous name for the Tcl package "Itcl") is one of the most widely used O-O system for Tcl.
		While there are over a dozen OO extensions for Tcl, [incr Tcl] is one of the compiled C extensions, which results in better performance than other, all-Tcl object systems.
		The book about incr tcl is the best tutorial there is; alas, incr tcl, like tclx, as well as a number of other quite widely used extensions, do not seem as widely documented as they could be.

		It certainly appears to be the most widely used, and certainly has proven its "industrial strength".

	Tcl- and [Incr tcl]- Based Applications for Astronomy and the Sciences
		Tcl consists of a powerful set of ``core'' commands that look like a cross between C functions and (t)csh commands.
		The general structure of these programs (bottom to top) is: low-level C code, mid-level C code, C code that registers mid-level functions as Tcl commands, and [incr tcl] classes corresponding to each type of data (logs, raw data, averaged data, configuration information, etc.).
		Tcl can now be considered a ``Web language'', since Tcl/Tk bytecode ``plug-ins'' have been created for Netscape, i.e., Netscape can be used to run Tcl/Tk applet scripts.

	Tcl - Wikipedia, the free encyclopedia
		Tcl (originally from "Tool Command Language", but nonetheless conventionally rendered as "Tcl" rather than "TCL"; and pronounced like "tickle") is a scripting language created by John Ousterhout.
		Tcl did not originally support object oriented syntax, being a functional language, but recent versions do support extensions which provide OO functionality, such as the XOTcl extension to Tcl.
		The Tcl programming language was created in the spring of 1988 by John Ousterhout while working at the University of California, Berkeley.

	Forum OpenACS Q&A: [incr] tcl abd AolServer
		The only thing I remember about incr tcl is that in AOLServer the global context is not maintained across threads, thereby you tend to end up with a little hack somewhere that essentially recreates all namespaces (objects) for each new interpreter..
		It's not really so much a problem with [incr] tcl or xotcl, as it is a problem with the single-threaded design of tcl that has been shoe-horned into the multi-threaded aolserver environment.
		This was achieved by essentially compiling in the [incr] Tcl stuff when building Aolserver.

	SWIG and Tcl
		Tcl is one of the easiest languages to compile extensions for.
		In Tcl 8.0, pointers are represented using a new type of Tcl object, but the string representation is the same (and is interchangable).
		While written in Tcl, these functions are building up a real C binary tree data structure that could be passed into other C function.

	Tcl/Tk Conference, 1998
		Michael was a great choice for keynote, as he showed some cool stuff that used Tcl under the hood, plus he's a cool guy and hung around for the whole conference and chatted with just about everybody.
		One surprise was that there was a lot of interest in the Tcl plug-in, as I (and apparently Scriptics) thought the plug-in was dying.
		A second theme that came through strongly was the use of Tcl for automated testing -- there was a whole session, and there were a number of people I talked to who used it for that purpose.

	Amazon.com: Tcl/Tk Tools: Books: Mark Harrison (Site not responding. Last check: 2007-10-13)
		The Tcl language and Tk toolkit, even alone, offer many benefits: They're easy to learn, capable of producing good interfaces quickly, great for prototyping applications, and they are infinitely customizable.
		The book is not written as a tutorial or introduction to Tcl, sagely pointing to John Ousterhout and Brent Welch's books for that role (although I've been thinking of experimenting with putting Tcl/Tk Tools in the hands of novices, to see what would happen.
		Less successful is the forward look that Harrison intended, toward "the plans the extension authors had for future enhancements and extensions." I assume this was in part a casualty of the realities of the publishing cycle; certainly many of the chapters appear to have been finished before the appearance a year ago of 7.6's betas.

	EvoX and CppTcl
		Cpptcl is a pair of loadable Tcl extensions which work fine under Unix and MacOS (and presumably other platforms too).

		A tertiary goal is to allow you to take either of the above forms of C++ in Tcl object functionality and wrap such an item inside an [incr Tcl] class.

	TCLLIB - Tcl Standard Library: snitfaq (Site not responding. Last check: 2007-10-13)
		A Tk widget is an object; it is represented by a Tcl command.
		It's a common technique in Tcl to modify an existing command by renaming it and defining a new command with the original name; the new command usually calls the renamed command.
		But not all Tcl objects follow Tk conventions, and not everything you'd to which you'd like to delegate a method is necessary an object.

		I'm almost tempted to read some web tutorials on Tcl and keep this book, but I can flip pages to review and reference material much faster with hard copy, and probably won't need [incr] extensions for my project.
