** Conference Paper **
Before submitting the final camera ready copy, remember to:

1. Manually equalize the lengths of two columns on the last page
of your paper;

2. Ensure that any PostScript and/or PDF output post-processing
uses only Type 1 fonts and that every step in the generation
process uses the appropriate paper size."
