Text GUI Toolkit (TGT) allows the programmer to forget about GUI implementation internals in their textmode application. Designing an interface now requires only specifying what kinds of controls (windows, labels, buttons, etc.) are needed, and where they should be placed. All dirty work, such as formatting, displaying, and handling keyboard (including controls switching, etc.) is done by TGT. TGT and TGT API were written in an OO way, but using pure C.
Statistical Traffic Analysis Kit is a set of command-line traffic analysis tools, designed to help a network administrator to see what is happening at a router at the moment. Unlike tcpdump(1), the STAK utilities use statistical and stream-oriented methods, and will never produce an output stream at a speed beyond human perception. The output is less accurate, however. STAK can estimate overall traffic rates, determine which nodes generate the most traffic, analyze traffic between the LAN and particular external systems, determine which connections generate the most traffic, and extract strings from packets.
masmz80 is a very lightweight assembler for the Zilog Z80 processor. Objects generated contain information about global symbols, unreferenced symbols, and sections that need to be relocated, so it's easy to write code in many files and reference one project files' symbols from another. Linking these objects using included mlinkz80 produces an image ready for burning on an (E)EPROM.
ECe is another clone of the ncurses-based editor that comes with the Midnight Commander (cooledit). Its main feature is simplicity. You don't have to learn lots of key shortcuts; in order to write text, you just have to type it on the keyboard. While preserving all the original cooledit features (like syntax highlighting or gpm mouse support), ECe offers a few useful enhancements: the ability to work with many files, reconfigurable keys and menus, tab-completion in file dialogs, friendlier default color scheme, and more.
Braa is a tool for making SNMP queries. It is able to query hundreds or thousands of hosts simultaneously, while being completely single-threaded. It does not need any SNMP libraries, as it is equipped with its own SNMP engine. However, it's good to have a complete SNMP package including "snmptranslate" installed somewhere, because for speed reasons, there is no ASN.1 parser in Braa, and all the SNMP OIDs need to be specified numerically.
