[dna-dev] End-of-line characters

[Randall Hauch]

John, let's wait to do this until we've frozen the code for the  
release.  That way everyone will have their code in and we'll  
hopefully eliminate any potential merge conflicts.  There's really no  
pressing need to get this done now, as long as we do it before we  
release.

Best regards,

Randall
