GNUlpr version 1.0 is a complete printing system based on LPR, and provides support for printer-specific options, GUI tools, and autoconfiguration. The 1.1 tree is a completely re-thought printing system. Rather than creating an all-powerful spooling daemon, it constructs a pipeline of "filter" programs to perform tasks (spooling, data stream type conversion, authentication, network protocols, etc.).
Gronk is a Web-based MP3 jukebox. It generates heavily-hyperlinked Web pages listing all of your ripped CDs, by extracting information from CDDB data. These Web pages allow easy selection of songs or albums to play, and when nothing has been explicitly selected, it selects songs randomly. Playback is done via either XMMS or mpg123.
GSI is an easy-to-use network audio system that gives applications, through a very simple API, sample playing with stereo, 3D, doppler effects, music playing (MIDI, HMP, MUS), and CD playing and ejecting/changing. GSI also contains a separately usable sound/music loading/saving/format conversion library libgsif, although saving/format conversion is not completely done. It is known to run on Linux, OpenBSD, and FreeBSD, with support for /dev/audio (8000Hz mono mulaw), OSS, ultrasound project drivers, and FreeBSD's pcm system (from 0.9.4 on).
Gwydion Dylan is a portable, optimizing Dylan compiler written in Dylan. It was originally written by the Gwydion Group at CMU and is now maintained by volunteers. Eventually, Gwydion Dylan is meant to become a top-notch tool for building complicated applications. Dylan is a dynamic, object-oriented language with four design goals: high performance, rapid prototyping, ease of use, and seamless support for using libraries written in C. Ports of Gwydion Dylan are available for many platforms.
HappyDoc is a tool for extracting documentation from Python source code. It differs from other such applications by the fact that it uses the parse tree for a module to derive the information used in its output instead of importing the module directly. This allows the user to generate documentation for modules which need special context to be imported.
HDLmaker generates hierarchical Verilog and VHDL code, PCB netlists, simulation and synthesis scripts/projects/make files, and schematics. It can translate Verilog/VHDL and HDLmaker projects into HTML, including extensive hyperlinking between the modules. It can also translate PADS PCB netlists into Verilog and VHDL and can do some simple VHDL to Verilog translations. HDLMaker synplifies the development of complex FPGAs and ASICs, and has extensive support for most Xilinx FPGAs.
