It still is "Usage: %s [<microcode file> | show-cpu-info]" The current one mean we can run one of: ./xen-ucode ucode.bin ./xen-ucode show-cpu-info The proposed help message in this patch mean we could have one of: ./xen-ucode ucode.bin ./xen-ucode show-cpu-info ./xen-ucode ucode.bin show-cpu-info But that last one is an error. Thanks,

Refactor xen-ucode tool by adding usage() to handle usage\help messages As we add more command options this will keep help\usage messages in common block [v2] 1- Improved message description. 2- Fixed formatting and indentation. 3- Error message to print to stderr.
