+.TH BUS-CHMOD 1 BUS-%VERSION%
+.SH NAME
+bus chmod - Change permissions on a bus
+.SH SYNOPSIS
+.B bus chmod
+.IR permissions
+.IR pathname
+.SH DESCRIPTION
+Change whom as access to a bus with an associated \fIpathname\fP.
+In the \fIpermissions\fP, the owner, the group, and others (not
+in group) are represented by the symbols \fBu\fP, \fBg\fP, and
+\fBo\fP, respectively. The \fIpermissions\fP string is imagined
+to have always be prefixed with an \fB=\fP. This symbols means
+that all user classes list after it, and only those classes, as
+permission to use the bus. Similarly the symbols \fB+\fP and
+\fB\-\fP can be used to grant and revoke access, respectively.
+The symbols \fB=\fP, \fB+\fP, and \fB\-\fP can be maked, and are
+interpreted from left to right.
