BashFAQ/050 - Greg's Wiki

Bash-Completion
We're currently working to get bash-completion at its best. This is what we plan to do in the near future: make a better homepage (you really want it, don't you? ;) ); make bash-completion dynamically load completions. Please join #bash-completion on irc.debian.org if you want any information. There you'll probably find luk__ (Luk Claes) or hanska (David Paleino), who might give you some more info
