-# Help() function, but these two features are incompatible: once
-# you've overridden the help text using Help(), there's no way to get
-# at the help texts from AddOptions. See:
-# http://scons.tigris.org/issues/show_bug.cgi?id=2356
-# http://scons.tigris.org/issues/show_bug.cgi?id=2611
-# This hack lets us extract the help text from AddOptions and
-# re-inject it via Help(). Ideally someday this bug will be fixed and
