If you are a TA of some course on ILMS.
You may need to fill score of every student's test or assignment.
This is soooo boring, so I write this script.
ruby ilms.rb demo.xls
Note that if you don't have the same structure with 'demo.xls'.
You need to customize the function 'read_score_from_file' in 'ilms.rb'.
