Dmitry,

If you want to have modified versions of the SE .se files, we can do 
that.  Take a look in the lib/SE directory where we keep patched 
versions of some these files.  In fact, there's already a live_rules.se 
in there.  Then when start_orcallator starts orcallator.se, it passes 
-I$libdir/SE/$SE_VERSION on the command line to pick up these versions 
before the standard SE files.

Regards,
Blair
