+.SH INCLUDE STATEMENT
+The LDIF parser has been extended to support an
+.B include
+statement for referencing other LDIF files.  The
+.B include
+statement must be separated from other records by a blank line.
+The referenced file is specified using a file: URI and all of its
+contents are incorporated as if they were part of the original
+LDIF file. As above, other URI schemes may be supported. For example:
+.LP
+.nf
+	dn: dc=example,dc=com
+	objectclass: domain
+	dc: example
+
+	include: file:///tmp/example.com.ldif
+
+	dn: dc=example,dc=org
+	objectclass: domain
+	dc: example
+.fi
+This feature is not part of the LDIF specification in RFC 2849 but
+is expected to appear in a future revision of this spec.
