AGVTool new-version and what-version do not correspond
===

When I do:

    agvtool new-version -all 99

It updates my Info.plist file. However, if I do this:

    agvtool what-version

I get an error that `CURRENT_PROJECT_VERSION` is not set. I would expect to get the `99` back which I have just set using agvtool.

Why does this not correspond. Do I have to use the plist command line tool in order to retrieve the current version of my app. Curiously `agvtool what-marketing-version` works fine. Ironically agvtool does not seem to have a version itself ;-)
