This looks like a copyleft license incompatible with the GPL.

However gl2ps.h has an explicit LGPL-compatibility clause, which makes
it usable in Octave:

I changed ‘non-copyleft’ to ‘fsf-free’ with a note saying this is a
copyleft license.

Thanks!

BTW Arun, could you create an account on Savannah so we can give you
commit access (make sure to upload on your Savannah account page the
OpenPGP key you will use to sign commits)?  That should be more
convenient for you.  :-)

Thanks in advance,

That's nice. Thanks! :-) I've created an account on Savannah.

Awesome, I’ve added you to the group.

Could you reply to this message signed with OpenPGP key
7F730343F2F09F3C77BF79D32E25EE8B61802BB3?

Please make sure to read ‘HACKING’ for the bits about commit access.

Thank you, and welcome aboard!  :-)

My outgoing SMTP relay (the mailjet.com smarthost) reencodes my mail
corrupting my PGP signature. And, since I am running my mail server on a
dynamic IP connection, I'm having difficulty sending mail directly to
debbugs.gnu.org. So, instead I have attached a text file signed with my
key. Will that do?

> Please make sure to read ‘HACKING’ for the bits about commit access.

Yes, I read `HACKING'.

Thank You! :-)
