# This file contains tests for the tclProc.c source file. Tests appear in
# the same order as the C code that they test. The set of tests is
# currently incomplete since it includes only new tests, in particular
# tests for code changed for the addition of Tcl namespaces. Other
# procedure-related tests appear in other test files such as proc-old.test.
#
# Sourcing this file into Tcl runs the tests and generates output for
# errors. No output means no errors were found.
