+
+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
+files:
+
+@table @option
+@item -p @var{password}
+@item --password=@var{password}
+Specifies the password to use to decrypt an encrypted SPSS system file
+or syntax file. If this option is not specified,
+@command{pspp-convert} will prompt interactively for the password as
+necessary.
+
+Be aware that command-line options, including passwords, may be
+visible to other users on multiuser systems.
+
+When used with @option{-a} (or @option{--password-alphabet}) and
+@option{-l} (or @option{--password-length}), this option specifies the
+starting point for the search. This can be used to restart a search
+that was interrupted.
+
+@item -a @var{alphabet}
+@item --password-alphabet=@var{alphabet}
+Specifies the alphabet of symbols over which to search for an
+encrypted file's password. @var{alphabet} may include individual
+characters and ranges delimited by @samp{-}. For example, @option{-a
+a-z} searches lowercase letters, @option{-a A-Z0-9} searches uppercase
+letters and digits, and @option{-a ' -~'} searches all printable ASCII
+characters.
+
+@item -l @var{max-length}
+@item --password-length=@var{max-length}
+Specifies the maximum length of the passwords to try.
+
+@item --password-list=@var{file}
+Specifies a file to read containing a list of passwords to try, one
+per line. If @var{file} is @file{-}, reads from stdin.
