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.
pkgusage lists all the packages you have installed on your system, along with a number telling you how many days ago you last accessed any of the files in the package. This could be useful for cleaning out your hard drive. Pkgusage works with RPMs and Debian packages, and is written to be easily portable to other package managers as well.
NoodeInstaller attempts to make distributing software easier for people who don't know how to use make and RPM. It is simpler and less powerful than these traditional methods, but it should suffice for most people. Its features include NoodleUnInstaller (for automating uninstalls), TkNIAK (a GUI program for making the install scripts), and InstallMaker (for making self-extracting installers).
Hamster Font Manager (HFM) helps you control the avaliability of fonts in all of the supported applications from a central place. It includes modules to support X11, Ghostscript, and TeX. A PostScript module handles PS Fonts while other fonts remain untouched by this program. It features a nice Tcl/TK GUI. For X11 configuration to work, this software has to run on the machine's own X Server.
