title: How can I find the version number of an iPhone app from the IPA?
body: <p>We're trying out a new way of specifying version numbers for our app.  I'd like to be able to check that the IPAs we're building have the version numbers we want.  How do I get the version number out of the IPA?</p>
  
  <p>Note - I'm not asking for a way of finding it from code inside the app; I've got a terminal open and the IPA file is built, and I want to know what to look for inside the IPA file.</p>
