[guardian-dev] Code License

Tue Jul 23 14:16:25 EDT 2013

It seems that we're compatible with the license and info that they include
in most of the code:
https://github.com/harlo/F5Android/blob/master/src/james/IJGreadme.txt
https://github.com/harlo/F5Android/blob/master/src/james/license.txt

They both basically write "In plain English:"

1. We don't promise that this software works.  (But if you find any bugs,
   please let us know!)

2. You can use this software for whatever you want.  You don't have to pay us.
3. You may not pretend that you wrote this software.  If you use it in a
   program, you must acknowledge somewhere in your documentation that

   you've used the IJG code.

I'm following up with them all, but also with the author of the
original F5 Algo, Andreas Westfeld, as his code (if he indeed has code
and not just theory), is not specifically broken out or labeled.

Question: if someone (Gaffga) converted all of Dr. Westfeld's f5 code
into java, does he have a claim to it?
