I'll let Geir speak for himself, but I think he was alluding to the use
of a user properties file:
<property file="${user.home}/.harmony.properties" />
that would *not* be checked in and would be read (if it existed or
ignored otherwise).

Which is exactly what you can achieve in a platform-independent way with
a property file as described above.

Read the list archive. Environment variables are platform-specific and
differ - if they exist - from platform to platform. Windows for example
treats environment variable names as case-insensitive but when ant reads
them from env.VaR you must get the case exactly right. Ant properties
are platform-independent and so will work the same everywhere.
