Dumps PyKota database's content.

command line usage :

  dumpykota [options] [filterexpr]

options :

  -v | --version       Prints dumpykota's version number then exits.
  -h | --help          Prints this message then exits.
  
  -d | --data type     Dumps 'type' datas. Allowed types are :
                       
                         - history : dumps the jobs history.
                         - users : dumps users.
                         - groups : dumps user groups.
                         - printers : dump printers.
                         - upquotas : dump user quotas.
                         - gpquotas : dump user groups quotas.
                         - payments : dumps user payments.
                         - pmembers : dumps printer groups members.
                         - umembers : dumps user groups members.
                         
                       NB : the -d | --data command line option   
                       is MANDATORY.
  
  -f | --format fmt    Dumps datas in the 'fmt' format. When not specified,
                       the format is to dump datas in the csv format (comma
                       separated values). All data dumped is between double
                       quotes. Allowed formats are :
                       
                         - csv : separate datas with commas
                         - ssv : separate datas with semicolons
                         - tsv : separate datas with tabs
                         - xml : dump data as XML
                         - cups : dump datas in CUPS' page_log format :
                                  ONLY AVAILABLE WITH --data history
                         
  -o | --output fname  All datas will be dumped to the file instead of
                       to the standard output. The special '-' filename
                       is the default value and means stdout.
                       WARNING : existing files are truncated !
                       
  Use the filter expressions to extract only parts of the 
  datas. Allowed filters are of the form :
                
         key=value
                         
  Allowed keys for now are :  
                       
         username       User's name
         groupname      Users group's name
         printername    Printer's name
         pgroupname     Printers group's name
         hostname       Client's hostname
         billingcode    Job's billing code
         
  Contrary to other PyKota management tools, wildcard characters are not 
  expanded, so you can't use them.
  
  NB : not all keys are allowed for each data type, so the result may be 
  empty if you use a key not available for a particular data type.
  
Examples :

  $ dumpykota --data history --format csv >myfile.csv
  
  This dumps the history in a comma separated values file, for possible
  use in a spreadsheet.
  
  $ dumpykota --data users --format xml -o users.xml
  
  Dumps all users datas to the users.xml file.
  
  $ dumpykota --data history printername=HP2100 username=jerome
  
  Dumps the job history for user jerome on printer HP2100 only.
