Octave contributors who are interested in evaluating student
applications and potentially co-mentoring a project (no commitment
required yet), please let me know to add you to the mentor team. We
will need at least 2 mentors per student we accept. Also update the
Wiki
https://wiki.octave.org/Summer_of_Code_-_Getting_Started with details
of any projects you have in mind.
