		Main entry point.  We expect the following properties:
			 os, ws, arch  - to be passed as ant properties or set as environment variables.
			 resultsBaseFolder - location to scp the resulting binaries to, usually a workspace containing the executable & launcher projects (eg: user@machine:~/workspace)
			 m_<os>.<arch> - name of a machine to ssh to for this os & arch
			 u_<os>.<arch> - optional user on the machine for this platform
			 j_<os>.<arch> - location of a jdk we can compile against
		We expect ssh keys to be set up so that we don't need passwords
		
		The j_<os>.<arch> properties work together with remote.sh, and are either
		   -javaHome /path/to/jdk
		or -java relative/path/to/jdk
