Firebird and MacOSX Uninstalls

MacOSX doesn't have an uninstall utility.
I use the following script to clean up Firebird installs on Leopard.
It should work on Tiger as well.
Would it make sense to include this in the Firebird package, along with a similar script for earlier versions of MacOSX (pre 10.4 for the powerpc builds)

#!/bin/sh
echo "Clean Services"
echo "Clean User"
dscl localhost -delete /Local/Default/Users/firebird
echo "Clean Group"
dscl localhost -delete /Local/Default/Groups/firebird
if [ -f "/Library/StartupItems/Firebird" ]; then
echo "Remove SuperServer StartupItem"
rm -fr /Library/StartupItems/Firebird
fi
if [ -f "/Library/LaunchDaemons/org.firebird.gds.plist" ]; then
echo "Remove Launchd"
launchctl unload /Library/LaunchDaemons/org.firebird.gds.plist
rm /Library/LaunchDaemons/org.firebird.gds.plist
fi
echo "Remove Framework"
rm -fr /Library/Frameworks/Firebird.framework
echo "Remove Receipt"
rm -fr /Library/Receipts/Firebird*.pkg

#Add the following for Firebird V2.5
echo "Remove /tmp/firebird"
rm -fr /tmp/firebird
