     Convenience for the lateral calls we make.  Use gwt.ant to
     descend into another directory, and this to call in the same build.xml.
     NOTE THE USE OF $TARGET, here and in common's gwt.ant.  This has the
     effect of dividing rules into subdirectory rules (using gwt.ant and
     sensitive to $target) and action rules (using call-subproject and
     setting $target)... but it is Bad for a subdirectory rule to depend
     on another one, as they are both sensitive to $target, but you probably
     mean that subdirB needed subdirA to be _built_, not $target'ed (tested,
     etc.)

     In other words, DO NOT USE DEPENDS=... IN A TARGET WITH GWT.ANT.
