+#!/usr/bin/env python
+#
+# Count statistics about SCons test and source files.  This must be run
+# against a fully-populated tree (for example, one that's been freshly
+# checked out).
+#
+# A test file is anything under the src/ directory that ends in
+# 'Tests.py', or anything under the test/ directory that ends in '.py'.
+#
+# A source file is anything under the src/engine/ or src/script/
+# directories that ends in '.py' but does NOT end in 'Tests.py'.  (We
+# should probably ignore the stuff in src/engine/SCons/Optik, since it
+# doesn't originate with SCons, but what the hell.)
+#
+# We report the number of tests and sources, the total number of lines
+# in each category, the number of non-blank lines, and the number of
+# non-comment lines.  The last figure (non-comment) lines is the most
+# interesting one for most purposes.
