Tiny Tcl 6.8 is a rommable, minimal Tcl implementation for embedded applications. Derived from the venerable Tcl 6.7 release, Tiny Tcl 6.8 has a solid Tcl feature set, excluding newer capabilities of Tcl 7 and 8 such as the bytecode compiler, namespaces, sockets, and async event handling, among others. Excluding C library functions, Tiny Tcl compiles down to less than 60 Kbytes on most machines, far smaller than any Tcl 7 or Tcl 8 derivatives.
TCL2FTP is an extension library for Tcl scripts which allows Tcl programs to perform FTP client and gateway actions. It fully supports the FTP/FXP protocols, is ready for use with SSL/TLS, and is compatible with glFTPd. It can run simple FTP commands, and it supports 25 simultaneous FTP sessions.
TclDTrace is a binding of libdtrace to the Tcl programming language. DTrace is a system profiling suite created by Sun Microsystems. It allows the user to profile a program without modifying its text, or even without the need to distract it if it is running. It consists of a set of library hooks called "providers", a set of tools, a C API (libdtrace), and its own specially crafted scripting language called D. A Tcl binding to libdtrace will allow users to run D scripts and process their results directly from Tcl.
