It does your dirty work, so keep it clean.
kh exposes plugins, known as fingers, as subcommands.
Usage:
kh [flags]
kh [finger] [arguments to a finger]
Available Meta-Commands:
version Print the version number of King's Hand
help C'mon, do I have to explain this one?
update [finger] Builds one or more fingers
By default, updates all
Flags:
-H, --hand-home="/Users/hitman/.kh": Home directory for kh
-v, --verbose[=false]: verbose output
Use "kh [finger] --help" for more information about a finger.
