panic: runtime error: index out of range - uru 0.8.0

[Former user]

I update uru to the latest version:

uru ver uru v0.8.0 [windows/386 go1.5]

I tried to access help via: >'uru admin help' and got error

panic: runtime error: index out of range

It's a bug in uru due to this code.

I need to update to be more robust for out-of-order subcommand invocations. Thank you for reporting

You should type uru help admin as in

The fix will be included in the next release.

C:\>uru ver
uru v0.8.1.alpha [windows/386 go1.5.2]

C:\>uru admin help
---> Use `uru help admin` to get admin sub-command help

C:\>uru admin foo
[ERROR] I don't understand the `foo` admin sub-command

[Jon]

Handle unknown admin sub-commands. Closes #85
