CommandLineParser issues

[jmezach]

While we were looking at integrating the commandline into for example our new VSCode extension we ran into a couple of interesting issues. For example, currently if you run:

augurk version

It will write out the version (with a CRLF probably, which doesn't work well cross platform), but will write that output to stderr, rather than stdout. This is probably baked into how the CommandLineParser library works, so not so easy to change on our side.

Perhaps it's worthwhile to have a look at this library: https://github.com/dotnet/command-line-api, which seems to be more closely aligned with what we need and has better support for cross-platform scenario's. Unfortunately they aren't shipping NuGet packages just yet.
