+ * Added "booktabs" argument to use the "\toprule", "\midrule", and
+ "\bottomrule" tags from the Latex "booktabs" package rather than
+ using "\hline" for all horizontal lines.
+ * Changed the "print.xtable()" arguments to use "getOption()"
+ to check the options for a default value. This was suggested
+ since "print.xtable()" has a lot of arguments that the user
+ will typically leave unchanged between tables.
