[PATCH 1/7] tools/kvm_stat: rework command line sequence and message texts

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Stefan Raspl <raspl@xxxxxxxxxx>

Make sure command line arguments are sorted alphabetically
everywhere, and adjusted existing texts for interactive command 's' to
become consistent with the long form --set-delay.
Throwing in some PEP8 fixes (all cosmetics) for good measure.
