+format (decrypted). Options for the output format are ignored in this
+case.

.IP "\fB\-O format\fR"
.IQ "\fB\-\-output\-format=\fIformat\fR"
interpreted. This option is necessary because old SPSS system files
do not self-identify their encoding.
.
+.IP "\fB\-k \fIvar\fR..."
+.IQ "\fB\-\-keep=\fIvar\fR..."
+Drops all variables except those listed as \fIvar\fR, and reorders the
+remaining variables into the specified order.
+.
+.IP "\fB\-d \fIvar\fR..."
+.IQ "\fB\-\-drop=\fIvar\fR..."
+Drops each \fIvar\fR listed from the output.
+.
+.SS "CSV Output Options"
+.PP
+These options affect only output to \fB.csv\fR and \fB.txt\fR files.
+.IP "\fB\-\-labels\fR"
+By default, \fBpspp\-convert\fR writes variables' values to the output.
+With this option, \fBpspp\-convert\fR writes value labels.
+.IP "\fB\-\-no\-var\-names\fR"
+By default, \fRpspp\-convert\fR\fR writes the variable names as the
+first line of output. With this option, \fBpspp\-convert\fR omits
+this line.
+.IP "\fB\-\-recode\fR"
+By default, \fBpspp\-convert\fR writes user-missing values as their
+regular values. With this option, \fBpspp\-convert\fR recodes them to
+system-missing values (which are written as a single space).
+
+.IP "\fB\-\-print\-formats\fR"
+By default, \fBpspp\-convert\fR writes numeric variables as plain
+numbers. This option makes \fBpspp\-convert\fR honor variables'
+print formats.
+
+.IP "\fB\-\-decimal=\fIdecimal\fR"
+This option sets the character used as a decimal point in output. The
+default is a period (\fB.\fR).
+
+.IP "\fB\-\-delimiter=\fIdelimiter\fR"
+This option sets the character used to separate fields in output. The
+default is a comma (\fB,\fR), unless the decimal point is a comma, in
+which case a semicolon (\fB;\fR) is used.
+
+.IP "\fB\-\-qualifier=\fIqualifier\fR"
+The option sets the character used to quote fields that contain the
+delimiter. The default is a double quote (\fB\(dq\fR).
+.
+.SS "Password Options"
+When the input file is encrypted, \fBpspp\-convert\fR needs to obtain
+a password to decrypt it. To do so, the user may specify the password
+with \fB\-p\fR (or \fB\-\-password\fR), or the name of a file containing a
+list of possible passwords with \fB\-\-password\-list\fR, or an
+alphabet of possible passwords to try along with a maximum length with
+\fB\-a\fR (or \fB\-\-password\-alphabet\fR) and \fB\-l\fR (or
+\-\-password\-length\fR). If none of these options is used,
+\fBpspp\-convert\fR prompts for the password. The password options
+are:
+.
.IP "\fB\-p \fIpassword\fR"
.IQ "\fB\-\-password=\fIpassword\fR"
-Specifies the password to use to decrypt encrypted SPSS system file
-or syntax file
-\fIinput\fR. If this option is not specified, \fBpspp\-convert\fR
-prompts for the password.
+Specifies the password to use to decrypt the input file.
.
.IP
On multiuser systems, this option may not be safe because other users
When these options are used, \fB\-p\fR may additionally specify a
starting point for the search.
.
+.IP "\fB\-\-password\-list=\fIfile\fR"
+Specifies a file to read containing a list of passwords to try, one
+per line. If \fIfile\fR is \fB\-\fR, reads from stdin.
+.
+.SS "Other Options"
.IP "\fB\-h\fR"
.IQ "\fB\-\-help\fR"
Prints a usage message on stdout and exits.
