ClasslistGenerator

 #!/usr/bin/perl
 
 #Classlist generator script
 # This script takes in a CSV file (such as those generated by Banner)
 # and creates a lst file which can be used to import students into a class. 
 
 #Currently the script assumes that the input file is a CSV file with the 
 #following fields
 ## STUDENT_ID, LAST_NAME, FIRST_NAME, MI, STREET1, STREET2, CITY, STATE, ZIP, textbox15, EMAIL, PHONE_1, GENDER, ETHNICITY, PHONE,  textbox23, textbox32, HONORS, TERM, SUBJECT, COURSE_NUM, SEC, DEPT, REG_STAT, TITLE, INSTRUCTOR
 
 #The first line of the CSV file should contain lables and data entries are 
 #only seperated by commas.  Currently the script strips off the student ID, the 
 #first and last names, the section number and email address and uses them to 
 # build the lst file.  The username for the student is the email address username.  
 
 #Those who are familiar with perl scripts should be able to modify this setup 
 #to deal with input files that have a different format.
