--debug=count
-Print a count of how many objects are created
-of the various classes used internally by SCons.
+Print how many objects are created
+of the various classes used internally by SCons
+before and after reading the SConscript files
+and before and after building targets.
This only works when run under Python 2.1 or later.

--debug=memory
Prints how much memory SCons uses
before and after reading the SConscript files
-and before and after building.
+and before and after building targets.
.TP
--debug=objects
- Allow more than one --debug= option to be set at a time.
+ - Change --debug=count to report object counts before and after
+ reading SConscript files and before and after building targets.
+
+ - Change --debug=memory output to line up the numbers and to better
+ match (more or less) the headers on the --debug=count columns.
