+@item -k @var{variable}@dots{}
+@itemx --keep=@var{variable}@dots{}
+By default, @command{pspp-convert} includes all the variables from the
+input file. Use this option to list specific variables to include;
+any variables not listed will be dropped. The variables in the output
+file will also be reordered into the given order. The variable list
+may use @code{TO} in the same way as in PSPP syntax, @i{e.g.}@: if the
+dictionary contains consecutive variables @code{a}, @code{b},
+@code{c}, and @code{d}, then @option{--keep='a to d'} will include all
+of them (and no others).
+
+@item -d @var{variable}@dots{}
+@itemx --drop=@var{variable}@dots{}
+Drops the specified variables from the output.
+
+When @option{--keep} and @option{--drop} are used together,
+@option{--keep} is processed first.
+
+@item -h
+@itemx --help
+Prints a usage message on stdout and exits.
+
+@item -v
+@itemx --version
+Prints version information on stdout and exits.
+@end table
+
+The following options affect CSV output:
+
+@table @option
+@item --recode
+By default, @command{pspp-convert} writes user-missing values to CSV
+output files as their regular values. With this option,
+@command{pspp-convert} recodes them to system-missing values (which
+are written as a single space).
+
+@item --no-var-names
+By default, @command{pspp-convert} writes the variable names as the
+first line of output. With this option, @command{pspp-convert} omits
+this line.
+
+@item --labels
+By default, @command{pspp-convert} writes variables' values to CSV
+output files. With this option, @command{pspp-convert} writes value
+labels.
+
+@item --print-formats
+By default, @command{pspp-convert} writes numeric variables as plain
+numbers. This option makes @command{pspp-convert} honor variables'
+print formats.
+
+@item --decimal=@var{decimal}
+This option sets the character used as a decimal point in output. The
+default is @samp{.}.
+
+@item --delimiter=@var{delimiter}
+This option sets the character used to separate fields in output. The
+default is @samp{,}, unless the decimal point is @samp{,}, in which
+case @samp{;} is used.
+
+@item --qualifier=@var{qualifier}
+The option sets the character used to quote fields that contain the
+delimiter. The default is @samp{"}.
+@end table

+The following options specify how to obtain the password for encrypted
