+.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 the input file.
+.
+.IP
+On multiuser systems, this option may not be safe because other users
+may be able to see the password in process listings.
+.
+.IP "\fB\-a \fIalphabet \fB\-l \fImax-length\fR"
+.IQ "\fB\-\-password-alphabet=\fIalphabet\ \fB\-\-password-length=\fImax-length\fR"
+These options are an alternative to \fB\-p\fR or \fB\-\-password\fR.
+They direct \fBpspp\-convert\fR to search for the correct password
+from the set of all passwords of symbols from \fIalphabet\fR (which
+may contain character ranges specified with \fB-\fR) and no more than
+\fImax-length\fR symbols long. For example, \fB\-a a-z \-l 5\fR
+checks all possible lowercase alphabetic passwords no more than 5
+characters long.
+.IP
+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.
