# 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.
