An off-list responder pointed me to

which seems to be saying that I should edit my App's Info.plist file to change the following lines:
<key>CFBundleTypeExtensions</key> <array> <string>*</string> </array>
to
<key>CFBundleTypeExtensions</key> <array> <string>xyz</string> </array> <key>LSIsAppleDefaultForType</key> <true/>
If I do this, then Drag-copy the App to the Applications folder, the magic takes effect. I'd rather keep the App where it is, however. Is there an easy way to tell OSX to pay attention to the Info.plist?
