GuitarTeX is based on the idea of Chord. It takes a Chord file containing Chordpro directives to produce good-looking and easy-to-play song sheets for guitarists in PostScript or PDF format. You can use all available LaTeX features and packages to create a songbook or a single song sheet as you like it. If you don't know very much about LaTeX you can create pstscript or PDF output automatically. There also is a Web-based version on the GuitarTeX homepage that produces HTML output, which may be used without installing anything on your local computer.
Gujin is a PC boot loader that can analyze your partitions and filesystems. It finds the Linux kernel images available, as well as other bootable partitions (for *BSD, MS-DOS, Windows, etc.), files (*.kgz) and bootable disk images (*.bdi), and displays a graphical menu for selecting which system to boot. It boots the Linux kernel using the documented interface, like LILO and GRUB, so it doesn't need any other pre-installed bootloader. It can also directly load gzipped ELF32 or ELF64 files, with a simple interface to collect real-mode BIOS data. There is no need to execute anything after making a new kernel: just copy the kernel image file into the "/boot" directory, with a standard name. Gujin is written almost entirely in C with GCC, and it fully executes in real mode to be as compatible as possible.
gwx is a GTK+ client for the wx200d(8) weather station server. It is unique in that it looks and feels like the real WX200 weather station hardware. An interactive, resizable picture of the hardware displays the current weather conditions in a window. Simply click the buttons to browse the weather data as you would on the real weather station. An alternate view of all data on one screen is also available.
Gyach is a GTK+-based Yahoo! Chat client which can use your existing Yahoo! logins for chatting in Yahoo! Chat. It supports colors, emotes/aliases, PMs, set status, remote user status display, ignore lists (local, non-Yahoo! based), a regex list of triggers to cause users to be automatically ignored, command-line recall via arrow keys, and tab completion of usernames.
