JCS-5-05. Joint Committee Print. Provides an explanation of tax legislation enacted in the 108th Congress. Arranged in chronological order by the date each piece of legislation was signed into law. This document, prepared by the staff of the Joint Committee on Taxation in consultation with the staffs of the House Committee on Ways and Means and the Senate Committee on Finance, provides an explanation of tax legislation enacted in the 108th Congress. The explanation follows the chronological order of the tax legislation as signed into law. For each provision, the document includes a description of present law, explanation of the provision, and effective date. Present law describes the law in effect immediately prior to enactment. It does not reflect changes to the law made by the provision or subsequent to the enactment of the provision. For many provisions, the reasons for change are also included. In some instances, provisions included in legislation enacted in the 108th Congress were not reported out of committee before enactment. For example, in some cases, the provisions enacted were included in bills that went directly to the House and Senate floors. As a result, the legislative history of such provisions does not include the reasons for change normally included in a committee report. In the case of such provisions, no reasons for change are included with the explanation of the provision in this document. In some cases, there is no legislative history for enacted provisions. For such provisions, this document includes a description of present law, explanation of the provision, and effective date, as prepared by the staff of the Joint Committee on Taxation. In some cases, contemporaneous technical explanations of certain bills were prepared and published by the staff of the Joint Committee. In those cases, this document follows the technical explanations. Section references are to the Internal Revenue Code unless otherwise indicated.

The Tcl language and Tk graphical toolkit are simple and powerful building blocks for custom applications. The Tcl/Tk combination is increasingly popular because it lets you produce sophisticated graphical interfaces with a few easy commands, develop and change scripts quickly, and conveniently tie together existing utilities or programming libraries.One of the attractive features of Tcl/Tk is the wide variety of commands, many offering a wealth of options. Most of the things you'd like to do have been anticipated by the language's creator, John Ousterhout, or one of the developers of Tcl/Tk's many powerful extensions. Thus, you'll find that a command or option probably exists to provide just what you need.And that's why it's valuable to have a quick reference that briefly describes every command and option in the core Tcl/Tk distribution as well as the most popular extensions. Keep this book on your desk as you write scripts, and you'll be able to find almost instantly the particular option you need.Most chapters consist of alphabetical listings. Since Tk and mega-widget packages break down commands by widget, the chapters on these topics are organized by widget along with a section of core commands where appropriate. Contents include: Core Tcl and Tk commands and Tk widgets C interface (prototypes) Expect [incr Tcl] and [incr Tk] Tix TclX BLT Oratcl, SybTcl, and Tclodbc
