Panic in "If it does actually panic, then ping the authors of LiteBox"

[Shnatsel]

Trying to run litebox_runner_linux_userland echo yay on a stock desktop Ubuntu installation causes the following panic:

thread 'main' (41447) panicked at litebox_runner_linux_userland/src/lib.rs:118:48:
called `Result::unwrap()` on an `Err` value: Os { code: 2, kind: NotFound, message: "No such file or directory" }

Referring to this line:

litebox/litebox_runner_linux_userland/src/lib.rs

Line 118 in 86e26df

let metadata = path.metadata().unwrap();

The function it's contained in has this comment:

litebox/litebox_runner_linux_userland/src/lib.rs

Lines 97 to 99 in 86e26df

	/// Can panic if any particulars of the environment are not set up as expected. Ideally, would not
	/// panic. If it does actually panic, then ping the authors of LiteBox, and likely a better error
	/// message could be thrown instead.

I could not find any documentation on the expected environment setup, so adding that and/or a better error message would be very welcome.

I'd like to fix this panic (improve executable path resolution / PATH lookup and replace unwrap/panic with a user-friendly error). I will submit a draft PR within 2 days. Could you please assign this issue to me? I will follow the repository's contribution process in the PR and sign the CLA as required.

Thanks for your interest in trying out LiteBox. We have not yet stabilized things and our APIs (and requirements from the environment) are actively under change (see the notice on our README), and thus have not yet put up documentation about this. Yes, we would like to improve this, for now the panics in that function will remain.
