.SH DESCRIPTION
+.VS 8.5
+Release 8.5 of Tcl supports the \fBinterp bgerror\fR command,
+which allows applications to register in an interpreter the command
+that will handle background errors in that interpreter. In older
+releases of Tcl, this level of control was not available, and applications
+could control the handling of background errors only by creating
+a command with the particular command name \fBbgerror\fR in the
+global namespace of an interpreter. The following documentation
+describes the interface requirements of the \fBbgerror\fR command
+an application might define to retain compatibility with pre-8.5
+releases of Tcl. Applications intending to support only
+Tcl releases 8.5 and later should simply make use of \fBinterp bgerror\fR.
+.VE 8.5
.PP
The \fBbgerror\fR command doesn't exist as built-in part of Tcl. Instead,
individual applications or users can define a \fBbgerror\fR
