A billing codes Manager for PyKota.

command line usage :

  pkbcodes [options] code1 code2 code3 ... codeN

options :

  -v | --version       Prints pkbcodes version number then exits.
  -h | --help          Prints this message then exits.
  
  -a | --add           Adds billing codes if they don't exist in PyKota's
                       database. If they exist, they are modified
                       unless -s|--skipexisting is also used.

  -d | --delete        Deletes billing codes from PyKota's database.
                       NB : the history entries with this billing code
                       are not deleted, voluntarily.

  -D | --description d Adds a textual description to billing codes.

  -l | --list          List informations about the billing codes.

  -s | --reset         Resets the billing codes' balance and page counters
                       to 0.

  -s | --skipexisting  In combination with the --add option above, tells
                       pkbcodes to not modify existing billing codes.

  code1 through codeN can contain wildcards if the --add option
  is not set.

examples :                              

  $ pkbcodes --add -D "My project" myproj

  Will create the myproj billing code with "My project"
  as the description.

  $ pkbcodes --delete "*"

  This will completely delete all the billing codes, but without
  removing any matching job from the history. USE WITH CARE ANYWAY !
  
  $ pkbcodes --list "my*"
  
  This will list all billing codes which name begins with 'my'.
