Just a small suggestion.

When running dotnet-script init in a directory that already has a launch.json file with other configurations, I found it a bit surprising that it totally overwrote what I had there:

$ dotnet-script init
Creating VS Code launch configuration file
...'/home/afk/temp/.vscode/launch.json' already exists' [Skipping]
...Use global tool launch config [Updated]
<snip>

I had experience with the tool running as non-global where it used [Updated] to mean modified and not overwritten.

So maybe changing the wording to something like

 Creating VS Code launch configuration file
 ...'/home/afk/temp/.vscode/launch.json' already exists' [Skipping]
-...Use global tool launch config [Updated]
+...Use global tool launch config [File Overwritten]

One other related small suggestion: maybe only highlight messages like [Updated] instead of [Skipping]. Highlighting the skipping messages (which don't feel important) trains me to ignore the highlights.

So instead of:

It would print something like:

I'm happy to make a PR, but the changes are very small and might take more effort to review rather than implement.

Thoughts?
