+# 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 begins with
+# 'test_' or ends in 'Tests.py', or anything under the test/ directory
+# that ends in '.py'.  Note that runtest.py script does *not*, by default,
+# consider the files that begin with 'test_' to be tests, because they're
+# tests of SCons packaging and installation, not functional tests of
+# SCons code.
+#
+# A source file is anything under the src/engine/ or src/script/
+# directories that ends in '.py' but does NOT begin with 'test_'
+# or end in 'Tests.py'.
+#
+# 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.
