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.
                       You can specify several names or wildcards, 
                       by separating them with commas.
  
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.
  
  $ repykota --printer "laser*,*pson" jerome "jo*"
  
  This will print the quota status for user jerome and all users
  whose name begins with "jo" on all printers which name begins
  with "laser" or ends with "pson".
  
  If launched by a non-root user, additionnal arguments representing
  users or groups names are ignored, and only the current user/group
  is reported.
