+Verify that rebuilds do not occur when SConsignFile(None) is used to
+put a .sconsign file in each directory and we subdvide the dependency
+tree with subsidiary *SConstruct* files in various subdirectories.
+
+This depends on using content signatures for evaluation of intermediate
+Nodes.  We used to configure this explicitly using
+TargetSignatures('content'), but we now rely on the default behavior
+being the equivalent of Decider('content').

+# That is, we chmod 0755 and us a "#!/usr/bin/env python" first
+# line for POSIX systems, and add .PY to the %PATHEXT% variable on
+# Windows.  If we didn't do this, then running this script with
+# suitable prileveges would create a .sconsign file in the directory
+# where the Python executable lives.  This can happen out of the
+# box on Mac OS X, with the result that the .sconsign statefulness
+# can mess up other tests.
