Generates print quota reports.

command line usage :

  repykota [options] 

options :

  -v | --version       Prints repykota's version number then exits.
  -h | --help          Prints this message then exits.
  
  -u | --users         Generates a report on users quota, this is 
                       the default.
  
  -g | --groups        Generates a report on group quota instead of users.
  
  -P | --printer p     Report quotas on this printer only. Actually p can
                       use wildcards characters to select only
                       some printers. The default value is *, meaning
                       all printers.
  
examples :                              

  $ repykota --printer lp
  
  This will print the quota status for all users who use the lp printer.

  $ repykota 
  
  This will print the quota status for all users on all printers.
