# 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
