Experimental Physics and Industrial Control System
Hi,
Disclaimer: I am not a lawyer and this is not legal advice. Also, I am not an
EPICS developer
That said, by reading the EOL I do not find any reason to believe it not being
GPL-compatible.
In fact, the only part that I had my doubts with was EOL's section 4c, but
doing a bit of research, I found that it is equivalent to similar clauses in
other officially GPL-compatible licenses [1] (see e.g. clause 4b of the
Apache2.0 license [2]).
In any case, I think it would be nice to actually submit the question to [3]
Cheers,
Carlos
