I failed to find a table of darwin version, os x version and os x name for a comment I wanted to leave on the docker port submission ticket [1]. Regarding this wiki edit the version table was my interest, perhaps there is a better place to document versions. I was hesitant to add ${os.major} without explaining what it meant in relation to the table. Perhaps changing the example to use os.major with a short comment like: # os.major is the left most dot separated number of the darwin version. You are a much better writer then I so feel free to move, edit or delete my work here. [1] https://trac.macports.org/ticket/43260#comment:13 Regards, Bradley Giesbrecht (pixilla)
