Call it like so:

$ irb
2.0.0-p247 :001 > require './ConfParser.rb'
 => true 
2.0.0-p247 :002 > f = File.open 'sample.txt'
 => #<File:sample.txt> 
2.0.0-p247 :003 > ConfParser.parse f
 => {"host"=>"test.com", "server_id"=>55331, "server_load_alarm"=>2.5, "user"=>"user", "verbose"=>true, "test_mode"=>true, "debug_mode"=>"off", "log_file_path"=>"/tmp/logfile.log", "send_notifications"=>true}
