Issue Number

#350

Overview

This PR replaces the --min-log-severity argument with two new switches:

• --quiet
• --verbose

These switches have the following semantics:

Switch	Help Text	Minimum Log Severity Level
--quiet	suppress all log output apart from errors	Error
--verbose	display debugging information in the log output	Debug
(none)	(default)	Info

Looking good.
Remains to update our CI to use a version of the bridge supporting this. I've updated my fork (used in CI) and now provide a pre-compiled binary that can be used in Travis:

https://github.com/KtorZ/cardano-http-bridge/releases/tag/v0.0.2

So, let's update travis.yml and remove the old file located inside our repository:

Arf... The file isn't executable?

It seems curl does not set the executable bit. I'm guessing that it doesn't have this capability.

I don't think the problem is cURL, the file isn't executable in a first place. Let me fix that 👍
