This is quite similar to how munin plugins works, and it's fare more 
compliant with FHS. It's also more resource-savy to evualuate the 
availability of a command (hence the usefulness of its completion 
function) at installation time, not each time a new shell is started.

I guess you still keep generic functions, as well as logic for sourcing 
individual completion files, in /etc/bash_completion ?
