Converting to DNG

[kj <koffiejunkielistlurker@koffiejunkie.za.net>]

Hi guys,

I'm surprised that I haven't seen anything to do this with.  Does anyone 
know of a tool to convert from camera manufacturers' RAW files to DNG?  
Converting from seems pretty well supported, but I can't find anything 
that will convert to DNG.

I would prefer something command-line orientated, so that I can script it.

Thanks
