ATMission is a Linux live CD distribution that lets you change any file on the CD. Unlike other live CDs where you can only change a carefully selected set of files placed on a ramdisk, it is based on the cowloop module and allows you to modify any file on the CD. You can even install additional RPMs and start programs at boot time. Changes can be saved in a file on the hard drive or a USB stick.
AVFS (A Virtual File System) is an easy-to-install system that enables all programs to access archived, compressed, remote, or other kind of virtual files without the need to recompile programs or the kernel. The following modules are currently implemented: tar, zip, rar, gzip, bzip2, ftp, http, dav, rsh/ssh, floppy, and many more.
AVInfo is a utility for displaying AVI, MPEG (1 and 2), OGM, MKV, and IFO (DVD) information. It returns the length of a clip, FPS, resolution, codec, audio and video bit rate, number of key frames, sound parameters, the number and type of streams, and the language for audio/subtitles. It then generates a file list with statistics (HTML, plain text, or CSV).
AVRDUDE (AVR Downloader Uploader) is a program for downloading and uploading the on-chip memories of Atmel's AVR microcontrollers. It can program the Flash and EEPROM. Where supported by the serial programming protocol, it can program fuse and lock bits. AVRDUDE also supplies a direct instruction mode, allowing one to issue any programming instruction to the AVR chip regardless of whether AVRDUDE implements that specific feature of a particular chip.
