Subject RE: Specifiying user properties file
Date Sun, 06 Nov 2005 03:40:45 GMT
You can also use the fact that Ant creates implicit properties from the 
Java  system properties and do something like this:

    <property file="${user.home}/user.properties"/>

This will load the user's specific properties file from their home 
directory.
