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