2.6. How can I join the development?
To join the development just code the feature you want to add and send
your patch in the mailing list. Before you start coding check the
your patch to the dev discussion group, open a ticket at the ngspice
Patches page or post a merge request
with Sourceforge. Before you start coding check the
latest development release of ngspice from our git repository.
It might be that your feature has already been implemented.
