+# findBadExternals.tcl --
+#
+#	This script scans the Tcl load library for exported symbols
+#	that do not begin with 'Tcl' or 'tcl'.  It reports them on the
+#	standard output.  It is used to make sure that the library does
+#	not inadvertently export externals that may be in conflict with
+#	other code.
+#
+# Usage:
+#
+#	tclsh findBadExternals.tcl /path/to/tclXX.so-or-.dll
