Yes, but "Sage is a free open-source mathematics software system
licensed under the GPL." You can replace "Free Software" in my previous
message with "GPL" if you like.
How closely does the notebook integrate with OpenSSL? Does it link to it
or do something equivalent?
If you combine GPL and GPL-incompatible software and redistribute the
result, you have a problem. An example:
1) I release libfoo under GPL3. In particular, that means that if you
link to my code and redistribute it, you may not impose additional
restrictions on your users.
2) You write a utility that encrypts foos. You use OpenSSL
to do this, and you link both OpenSSL and libfoo.
3) You distribute the work.
Now, do your users have to abide by the OpenSSL advertising clause?
All advertising materials mentioning features or use of this
software must display the following acknowledgement:
"This product includes cryptographic software written by
Eric Young (e...@cryptsoft.com)"
The word 'cryptographic' can be left out if the rouines from the
library being used are not cryptographic related :-).
If not, you've violated its license. If so, you've violated mine.
