Hi,
Looking forward to it, also feel free to post even in this mailing list if
you change idea, find a deadlock don't worry if something said is not
proper this is also a research project to find the most suitable model for
crystalspace too.

I've got your account account activated on sourceforge so you can commit to
crystal space repo (your branch of the repo is under
http://sourceforge.net/p/crystal/code/HEAD/tree/CS/branches/soc2013/planetsim/remember
to keep it merged with trunk so it will be easier to merge back,
also keep commits of autogenerated files separate (personally i'd also
separate commits to configuration files as those are most likely to have
merge troubles. As always i invite you to also join irc as it would allow
even other people who seems to not like the mailing list to help you :)

Keep up the good work!
