Try to commit my first iPhone application to Subversion found that there's "code signing identity" section in my xcode project.pbxproj file.

```
CODE_SIGN_IDENTITY = "iPhone Developer: my username here...;
"CODE_SIGN_IDENTITY[sdk=iphoneos*]" = "iPhone Developer: above...";

```

The issue is, in our team we use different provisioning which bound to our device. So when other want to run the code on device, they have to change this line. We can share one provisioning to across this, but that way have several downside. Is there any other way to solve it? i.e. include code signing section to another file which not commit to SVN?
