 .Sh SYNOPSIS
 .Nm sftp-server
+.Op Fl ehR
+.Op Fl f Ar log_facility
+.Op Fl l Ar log_level
+.Op Fl u Ar umask
 .Sh DESCRIPTION
 .Nm
 is a program that speaks the server side of SFTP protocol
 to stdout and expects client requests from stdin.
 .Nm
 is not intended to be called directly, but from
-.Xr sshd 8 
+.Xr sshd 8
 using the
 .Cm Subsystem
 option.
+.Pp
+Command-line flags to
+.Nm
+should be specified in the
+.Cm Subsystem
+declaration.
 See
-.Xr sshd 8 
+.Xr sshd_config 5
 for more information.
-.Sh HISTORY
+.Pp
+Valid options are:
+.Bl -tag -width Ds
+.It Fl e
+Causes
+.Nm
+to print logging information to stderr instead of syslog for debugging.
+.It Fl f Ar log_facility
+Specifies the facility code that is used when logging messages from
+.Nm .
+The possible values are: DAEMON, USER, AUTH, LOCAL0, LOCAL1, LOCAL2,
+LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7.
+The default is AUTH.
+.It Fl h
+Displays
+.Nm
+usage information.
+.It Fl l Ar log_level
+Specifies which messages will be logged by
+.Nm .
+The possible values are:
+QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1, DEBUG2, and DEBUG3.
+INFO and VERBOSE log transactions that

+performs on behalf of the client.
+DEBUG and DEBUG1 are equivalent.
+DEBUG2 and DEBUG3 each specify higher levels of debugging output.
+The default is ERROR.
+.It Fl R
+Places this instance of
+.Nm
+into a read-only mode.
+Attempts to open files for writing, as well as other operations that change
+the state of the filesystem, will be denied.
+.It Fl u Ar umask
+Sets an explicit
+.Xr umask 2
+to be applied to newly-created files and directories, instead of the
+user's default mask.
+.El
+.Pp
+For logging to work,
+.Nm
+must be able to access
+.Pa /dev/log .
+Use of
+.Nm
+in a chroot configuration therefore requires that
+.Xr syslogd 8
+establish a logging socket inside the chroot directory.
