+The VARIABLES subcommand specifies the dependent variables and the
+independent variable to use as factors for the analysis. Variables
+listed before the first BY keyword are the dependent variables.
+The dependent variables may optionally be followed by a list of
+factors which tell PSPP how to break down the analysis for each
+dependent variable. The format for each factor is
+@display
+var [BY var].
+@end display
+
+
+The STATISTICS subcommand specifies the analysis to be done.
+DESCRIPTIVES will produce a table showing some parametric and
+non-parametrics statistics. EXTREME produces a table showing extreme
+values of the dependent variable. A number in parentheses determines
+how many upper and lower extremes to show. The default number is 5.
+
+
+The PLOT subcommand specifies which plots are to be produced if any.
+
+The CINTERVAL subcommand specifies the confidence interval to use in
+calculation of the descriptives command. The default it 95%.
+
+The TOTAL and NOTOTAL subcommands are mutually exclusive. If NOTOTAL
+is given and factors have been specified in the VARIABLES subcommand,
+then then statistics for the unfactored dependent variables are
+produced in addition to the factored variables. If there are no
+factors specified then TOTAL and NOTOTAL have no effect.
+
+@strong{Warning!}
+If many dependent variable are given, or factors are given for which
+there are many distinct values, then @cmd{EXAMINE} will produce a very
+large quantity of output.
