+
+In this example, no configuration will be written or read,
+and the build will only use timestamps (no cache files
 and no signatures). There is no build directory either.
 
 To build, use "./ebd"
 
-Note from the author: using signatures is of course much better
-this example is for research purposes only
+
+Although the wscript file only declares a build function,
+the system performs a configuration internally to check for
+a C compiler. The configuration and build context classes are
+overridden to hide output messages and to avoid creating cache
+files.
+
+The task class is monkey-patched so that all existing build tasks
+will execute without using signatures (only file timestamps are considered).
+Implicit dependencies such as headers are still computed automatically.
