-# This file, proc-old.test, includes the original set of tests for Tcl's
-# proc, return, and global commands. There is now a new file proc.test
-# that contains tests for the tclProc.c source file.
-#
-# Sourcing this file into Tcl runs the tests and generates output for
-# errors. No output means no errors were found.
