Executing `art` panics

[matthiasbeyer]

When executing art (without commands or flags) I get:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Error(CmdError("\u{1b}[32martifact\u{1b}[0m 1.1.0-beta001\nhttps://github.com/vitiral/artifact\nThe requirements tracking tool made for developers.

Expected behaviour

Printing either an error or the help text or executing a default command.

Bizare -- it is atempting to write the help message but it is instead panicing.

Is this happening on stable or beta (or both)?

[matthiasbeyer]

This happens on the installation from crates.io, so beta I suppose.

[vitiral]

this still exists in 2.0.1

I'm still seeing this on 2.1.4 Darwin downloaded from Github Rleases. Different error though.
