Update contrib.
     1 # This file contains tests for the tclVar.c source file. Tests appear in
     2 # the same order as the C code that they test. The set of tests is
     3 # currently incomplete since it currently includes only new tests for
     4 # code changed for the addition of Tcl namespaces. Other variable-
     5 # related tests appear in several other test files including
     6 # namespace.test, set.test, trace.test, and upvar.test.
     7 #
     8 # Sourcing this file into Tcl runs the tests and generates output for
     9 # errors. No output means no errors were found.
