# 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.
