# Functionality covered: this file contains slightly modified versions of
# the original tests written by Mike McLennan of Lucent Technologies for
# the procedures in tclNamesp.c that implement Tcl's basic support for
# namespaces. Other namespace-related tests appear in namespace.test
# and variable.test.
#
# Sourcing this file into Tcl runs the tests and generates output for
# errors. No output means no errors were found.
