I've been working on a series of tools to interact with Java Avro from the command-line (stuff like inducing schemas, generating the specific code, etc.) I've been putting off adding significant command-line argument handling to these, but I'm getting to a point where I need it.
I'm tempted to go with http://jopt-simple.sourceforge.net/ or http://jewelcli.sourceforge.net/ . I don't really like http://commons.apache.org/cli/ as much. Does anyone have opinions or prior experience with these libraries? -- Philip
