command line arguments with Scala

Goal: Make sense of command-line arguments from a Scala program

I like "scala-optparse", as it's simple. I tried a few others, first:

Getting one big jar out of an sbt Scala project

Goal: Get a jar that includes all the dependencies of a Scala SBT project, so I can run

> java -jar MyAwesomeApplication.jar

instead of running through SBT (slow).

I used

https://github.com/eed3si9n/sbt-assembly

with the following configuration in build.sbt:

"""

import AssemblyKeys._ // put this at the top of the file

seq(assemblySettings: _*)

// Remove cryptographic bullshit that can make Java security freak out.
// Even though we "remove" the manifest, a manifest still ends up in the
// jar, so it looks like another is generated. If we don't remove it, we get a
// complaint about multiple manifests.
excludedFiles in assembly := { (bases: Seq[File]) =>
  bases flatMap { base =>
    (base / "META-INF" * "*").get collect {
      case f if f.getName.toLowerCase.contains(".rsa") => f
      case f if f.getName.toLowerCase.contains(".dsa") => f
      case f if f.getName.toLowerCase.contains(".sf") => f
      case f if f.getName.toLowerCase == "manifest.mf" => f
    }
  }}
"""

I had to remove the cryptographic keys (what I'm doing above) because I was getting a java.lang.SecurityException, so I adapted the suggestions on this site:

Thank you, Google translate!

Also, I tried https://github.com/retronym/sbt-onejar first, but without success (it seems to use an outdated version of One-JAR).
