sl@0: # This file contains the original set of tests for Tcl's incr command.
sl@0: # Since the incr command is now compiled, a new set of tests covering
sl@0: # the new implementation is in the file "incr.test". Sourcing this file
sl@0: # into Tcl runs the tests and generates output for errors.
sl@0: # No output means no errors were found.
