Additional Resources
LATEX is a difficult program to master. If you’ve used
that software, and this document didn’t help or some
items were not explained clearly, we recommend you read
Michael Shell’s excellent document (testflow doc.txt V1.0a
2002/08/13) about obtaining correct PS/PDF output on
LATEX systems. (It was written for another purpose, but it has
general application as well). It is available at www.ctan.org
in the tex-archive.
Acknowledgments
AAAI is especially grateful to Peter Patel Schneider for his
work in implementing the aaai.sty file, liberally using the
ideas of other style hackers, including Barbara Beeton. We
also acknowledge with thanks the work of George Ferguson
for his guide to using the style and BibTeX files — which
has been incorporated into this document — and Hans Gues-
gen, who provided several timely modifications, as well as
the many others who have, from time to time, sent in sug-
gestions on improvements to the AAAI style.
