CONTENTS: blt itcl tclx blt: * This is the version 1.7 release of the blt library. It is an blt: extension to Tk toolkit (it requires no patching of the Tcl blt: or Tk libraries). blt: blt: blt: blt: blt: blt: blt: blt: itcl: * [incr Tcl] - version 1.5 itcl: itcl: [incr Tcl] adds object-oriented programming facilities to Tcl. It itcl: was NOT designed as yet another whiz-bang object-oriented programming itcl: language; indeed, it is patterned somewhat after C++. It was designed itcl: to support more structured programming in Tcl. Scripts that grow itcl: beyond a few thousand lines become extremely difficult to maintain. itcl: [incr Tcl] attacks this problem in the same way that any object- itcl: oriented programming language would, by providing mechanisms for itcl: data encapsulation behind well-defined interfaces. itcl: tclx: * TclX - Extended Tcl: Extended command set for Tcl (v. 7.3b) tclx: tclx: Extended Tcl is a superset of standard Tcl and is built alongside the tclx: standard Tcl sources. Extended Tcl has three basic functional areas: tclx: A set of new commands, a Tcl shell (i.e. a Unix shell-style command tclx: line and interactive environment), and a user-extensible library of tclx: useful Tcl procedures, any of which can be automatically loaded on the tclx: first attempt to execute it. tclx: tclx: tclx:
