bash completions

[Aidan Gauland]

Hello,

Has anyone here, by any chance, written their own TAB-completions for bash?  I 
want to make a very simple one to only consider files ending in ".image" to be 
completions for the command "squeak" (and another similar one for a different 
program).  So I could type "squeak TAB" and the only image file in the current 
directory will show up.

I tired looking around on the web, and found nothing easy to understand (and 
some things that only introduced the TAB key to newbies).

Thanks,
Aidan
