It's actually a two step process:

   exu eu.ex -c sieve8k.exw
   exu dis.ex sieve9k

First, you have to shroud it such that it doesn't delete anything (that's
what the -c does).  Then you disassemble the *.oe file (the extension
is optional when running dis.ex).  Then dis.ex will output a file with
a .dis extension, which is a text file with the disassembled output.  If
you have "with trace" on in the code, you'll be able to see the lines
whenever a STARTLINE op is called.
