[sane-devel] Pure java sane interface

[Andi McLean]

I'm the maintainer / author of JSane.
I've been meaning to release JSane under the lgpl but not had time to alter 
the comments, sourceforge etc.

If you wish to use JSane, under the LGPL you have my permission to do so.
If you need written permission e-mail me  andi at pandagrove dot co dot uk
and we'll sort something out.

Cheers
Andi

BTW pointers and strings do get a little messy when using SANED.
