+<i>Note: In version 1.5 of Routino the --slim option has been removed but at
+compilation time a separate program called <em>planetsplitter-slim</em> is
+created that operates in slim mode. In slim mode the temporary files and
+database files are read as needed rather than being mapped into memory. This
+allows a database size greater than 2 GB on 32-bit machines or usage with little
+or no virtual memory (e.g. some virtual machines). The penalty for this is that
+the program takes about four times as long to run.</i>
