A Ruby gem which takes the pain of continuously reading data from a serial port away and lets you focus on dealing with the data received. This was written specifically for reading in data from an ID-20 RFID card reader and running custom scripts to automatically perform various tasks when patrons scanned their badge at the [MN Mill](http://mnmill.org) (logging attendance, etc). Custom scripts are loaded from `ENV["HOME"]/millworker/tasks` and are executed in alphabetical order. Each script is executed with the ID of the badge passed in as an argument. For example, a script called `tweet_id.rb` existed in the afformentioned directory, it would be executed as if you had opened up a command terminal and typed `tweet_id.rb RFID_TAG_ID_HERE`.
