bbkeys is the keygrabber for the Blackbox window manager. bbkeys handles all keybindings and keyboard shortcuts for Blackbox. It uses Blackbox's Image classes for rendering its look and feel, so bbkeys will draw itself to match whatever Blackbox style is used. It is highly configurable via the bbconf GUI utility, the included bbkeysconf.pl perl script, or via hand-editing bbkeys's config file.
bfr maintains a buffer of data collected from stdin, emitting the data to stdout. It will both read and write at the speed each stream can handle, and allows you to set thresholds of when to start outputting and inputting again (after reaching a full buffer), the size of the buffer, as well as monitor content/throughput with an optional progress-bar. It also includes bfp, a variant especially written to play audio data using /dev/dsp.
