BSD license + should
(please CC me on replies)
I came across the Molspin package , which has a standard BSD 3-clause
license plus this following fourth clause[2,3]:
|4. Every use of the source code or binary form of the software should
|acknowledge the following publication:
| MolSpin - Flexible and Extensible General Spin Dynamics Software
| Claus Nielsen & Ilia A. Solov'yov
| Note: The paper is submitted to Journal of Chemical Physics (Special
| issue on spin chemistry, 2019).
I am wondering whether this is DFSG-free as this fourth clause is a
should, not a must (and it is good academic practise to cite anyway)?
If not, can you suggest a rephrasing of this clause that would make it
DFSG-free, but be similar in spirit (i.e. nudge the user to cite the
package if they publish results based on its use)?
 Above is the one included in the release file, the one on the
website is very similar though, it just has a link to the publication
instead of mentioning it directly
