like this chapter, since it gives me working sample directly as new to ruby

Comments: 1. the example is using symbol instead of string, will be good to describe what’s benefit using symbol here 2. it goes directly to complicate yaml config file in p96 (b 6_0), probably add one more example like using array in yaml, then mention it can map to all ruby object.

Yeah, I thought about these, but wanted to avoid too much generic Ruby stuff, so I could focus on the command-line stuff.

For symbols/strings, it’s pretty common in ruby to use symbols as hash keys.

YAML is a pretty straightforward format, and it’s used for a lot of configuration files in Ruby. If you want to learn more about it, there’s the official yaml site (http://www.yaml.org), or you could just play around with the the YAML library (http://www.ruby-doc.org/stdlib-1.9.3/libdoc/yaml/rdoc/index.html) that comes with Ruby in IRB to see how it works.
