Location of swift.properties
Swift searches for swift.properties files in multiple locations:
1. The etc/swift.properties file included with the Swift distribution.
2. $SWIFT_SITE_CONF/swift.properties - used for defining site templates.
4. swift.properties in your current directory.
5. Any property file you point to with the command line argument "-properties

To verify what files are being read, and what values will be set, run:
