[gmx-developers] DCD / Licence

[Erik Lindahl]

Hi,

I think the kosher thing to do (at least that's what I've done when  
combining in things from more permissive licenses) is:

1) Since gromacs as a *package* is licensed under GPL/LGPL, add the  
normal Gromacs copyright header at the top of the file. This is just  
so we can make clear there is a single license for the entire package!

2) Obviously, keep the original license and document what part of the  
code it concerns (i.e, what routines we included). The best thing is  
probably to keep it a separate file, but just in case we were ever to  
mix in code from two other distributions.

3) In the sake of fairness, I usually write a comment that since we  
got this code under an even more permissive license, anybody else in  
turn is allowed to use our modifications too under that license  
instead of GPL if they prefer to. Not necessary, but it's the decent  
thing to do, IMHO.


Cheers,

Erik
