+ (description
+ "The @code{sqldf} function is typically passed a single argument which is
+an SQL select statement where the table names are ordinary R data frame names.
+@code{sqldf} transparently sets up a database, imports the data frames into
+that database, performs the SQL statement and returns the result using a
+heuristic to determine which class to assign to each column of the returned
+data frame. The @code{sqldf} or @code{read.csv.sql} functions can also be
+used to read filtered files into R even if the original files are larger than
+R itself can handle.")
