Document how to use CLI for configuration

I can't seem to find how to use the CLI for configuration, despite the fact the README says it's an available source.

Will do.

For now, you'll have to refer to the tests. https://github.com/npryce/konfig/blob/master/src/test/kotlin/com/natpryce/konfig/cli_tests.kt

I played with it a little bit and it seems that it is not possible to mark a CommandLineOption as optional. This is unfortunate especially with the possibility of using the overriding function so that proper default values can be provided through another Configuration.

Did I miss something?

Use the getOrElse or getOrNull methods to get optional properties

Sorry, my mistake. I did not recognize that the exception I got had been caused by the property access. I thought that parsing would generate the exception.

No problem. The library does need better documentation!

This was in 2017 and the documentation is still not updated, of this ticket closed.
