+Subject: X bitmap for bash
+
+        Since other GNU software comes with its very own X bitmap, I
+     thought it was about time bash had one too & here it is!  To use,
+     stick the stuff after my signature in a file <path>/bash.xbm.  If
+     using a twm window manager, insert the lines:
+
+IconDirectory           "<path>"
+Icons {
+        "<xterm title>" "bash.xbm"
+}
+        in your ~/.twmrc file.  The <xterm title> can be a prefix, so if
+     you have titles "bash@machine", the prefix "bash" will do.  I'm not
+     familiar enough with other window managers, but they should be
+     similar.
+
+        If you like it, you're welcome to it...
+
+        Simon.
