How are you traversing the directory you pass in on the command line ?

Thank you. I think I'll also look into the YAML::Store a bit more. Where 
would I find a complete reference for it? Ruby-doc at 
http://www.ruby-doc.org/stdlib-1.9.3/libdoc/yaml/rdoc/YAML/Store.html 
only provides basic info.

Since the parent is PStore, may I just use that as a full reference?

I think the confusing part in all this is my perception of the storage 
files related to these functionalities and their manipulation (storing 
and loading of objects).
