Parse conf file for CLI tool


I’m pretty new to ruby and want to program some some linux shell tools
in ruby as exercise. For these tools I want to be able to specify
options as parameters on the command line or in a config file.
I already discovered OptionParser to parse the command line options.

Can someone give me suggestions which classes to look at to simplify the
task of parsing a configuration file for options?

a: b

That’s exactly what I was looking for. Thanks!
