+ * tools/findBadExternals.tcl: Added this script, which locates
+ external symbols that do not begin with 'Tcl' or 'tcl' and hence
+ might be in conflict with other link libraries. Thanks to George
+ Peter Staplin for the idea and the initial version of the script.

+# 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.
