7.6 Distribution NeoTcl is a supported bundle of Tcl 7.6 and extensions. This is a compressed tar file of the distribution. This may be a unix-only package. This package includes a realtime task manager, a hardware channel mapping facility, a shared data region for all interpreters and tasks, and a set of numerical tools for matrix manipulation. These tools are available in binary form for the macintosh, windows, and Linux.
Source is available for other platforms.
Yet another OO system for tcl, pure tcl. Generic option processing routines. This is UNIX only, but it did form the basis of the 8.1 threading support. This extension adds a red-black tree as a new data type. This is an efficient form of lookup table.
