+.SH NAME
+bus - A simple daemonless system for broadcasting messages locally
+.SH DESCRIPTION
+\fBbus\fP is a simple interprocess communication system for broadcasting messages to other processes on the same machine. \fBbus\fP does not use any daemon. Instead all communication and synchronisation is managed using System V (XSI) semaphores and System V (XSI) shared memory.
+
+The command \fBbus create\fP can be used to new buses. By convention, buses should be stored in \fIXDG_RUNTIME_DIR/bus\fP, this is what \fBbus create\fP does if no pathname is given. The pathname of the bus should be tracked using \fIBUS_X\fP, where \fIX\fP is replaced with either:
+.TP
+.IR GENERIC
+For the bus used in generic cases. That is all but the cases of the buses listed below.
+.TP
+.IR AUDIO
+For the bus used in with the audio subsystem is involved.
+.TP
+.IR VIDEO
+For the bus used in with the video subsystem is involved.
+.TP
+.IR INPUT
+For the bus used in with the input subsystem is involved.
+.TP
+.IR FILES
+For the bus used in with the storage subsystem is involved.
+.SH
+
+Messages broadcasted on a bus cannot be longer than 2047 bytes, excluding NUL-termination. Message should be encoded in UTF-8, and most not contain the NUL-character.
+
+Broadcasted message should start with the process ID whence the message originated, followed by a single regular space.
