+.Sh NAME
+.Nm setextattr
+.Nd set a named extended attribute
+.Sh SYNOPSIS
+.Nm setextattr
+.Ar attrname
+.Ar filename
+.Ar attrvalue
+.Sh DESCRIPTION
+.Nm
+is a user tool to set a named extended attribute on a file or directory to
+the provided string.
+The
+.Ar attrname
+argument should be the name of the attribute,
+.Ar filename
+the name of the file or directory to set the attribute for, and
+.Ar attrvalue
+a string to store in the attribute.
+.Nm
+will store the string in the file's attribute.
+In order for
+.Nm
+to succeed, the attribute service must be available on the file system,
+and appropriate privilege may be required.
+.Sh EXAMPLES
+.Pp
+.Dl # setextattr md5 /kernel `md5 -q /kernel`
+.Pp
+Set the ``md5'' extended attribute on the file /kernel to the string
+containing the output of ``md5 -q /kernel''.
+.Sh SEE ALSO
+.Xr extattrctl 8 ,
+.Xr getextattr 8 ,
+.Xr extattr 9
+.Sh HISTORY
+Extended attribute support was developed as part of the TrustedBSD Project,
+and introduced in FreeBSD 5.0.
+It was developed to support security extensions requiring additional labels
+to be associated with each file or directory.
+.Sh AUTHORS
+Robert N M Watson
+.Sh BUGS
+.Nm
+can only be used to set attributes to strings.
