http://www.ruby-doc.org/docs/ProgrammingRuby/ is a good start. Read the 
bits about regular expressions.

You can match the line with a regular expression, and use capture groups 
(in parentheses) to pick out the bits you want.

>> str = "hello/to/you"
=> "hello/to/you"
>> str =~ %r{(.*)/(.*)}
=> 0
>> $1
=> "hello/to"
>> $2
=> "you"
