Since iTunes does not give you a lot of information via print or export of your apps, I wrote a little shell script to retrieve information from the app files themselves.
The script creates and opens a .csv file. To correctly display the columns, choose 'semicolons' as the column delimiter in your csv viewer (e.g. OpenOffice Calc).
You can choose what information to retrieve by commenting/uncommenting them in the Attributes definition at the beginning of the script.
To run the script do the following: [crarko adds: Note that the path to the Mobile Applications folder may be different depending on your previous upgrade path(s), for example mine was located at ~/Music/iTunes/iTunes Music/Mobile Applications. Just be sure to put the script in the same folder as the app (.ipa) files.]
