I consider the first three as ready to pull (they form my master branch at the repo above). The fourth commit is just preparing the fifth. The fifth commit implements a new export method that I use often. The error handling isn't well tested, just because I don't usually run into merge conflicts in my series :-)

I look forward to comments, especially for the last commit.

For review purposes I send the patches as a reply to this mail.

Best regards Uwe
