    41 A turn key tool for PyKota. When launched, this command will initialize 
    42 PyKota's database with all existing print queues and some or all users. 
    43 For now, no prices or limits are set, so printing is fully accounted 
    44 for, but not limited. That's why you'll probably want to also use 
    45 edpykota once the database has been initialized. 
    46  
    47 command line usage : 
    48  
    49   pkturnkey [options] [printqueues names] 
    50  
    51 options : 
    52  
    53   -v | --version       Prints pkturnkey version number then exits. 
    54   -h | --help          Prints this message then exits. 
    55  
    56   -c | --doconf        Give hints about what to put into pykota.conf 
    57  
    58   -d | --dousers       Manages users accounts as well. 
    59  
    60   -D | --dogroups      Manages users groups as well. 
    61                        Implies -d | --dousers. 
    62  
    63   -e | --emptygroups   Includes empty groups. 
    64  
    65   -f | --force         Modifies the database instead of printing what 
    66                        it would do. 
    67  
    68   -u | --uidmin uid    Only adds users whose uid is greater than or equal to 
    69                        uid. You can pass an username there as well, and its 
    70                        uid will be used automatically. 
    71                        If not set, 0 will be used automatically. 
    72                        Implies -d | --dousers. 
    73  
    74   -U | --uidmax uid    Only adds users whose uid is lesser than or equal to 
    75                        uid. You can pass an username there as well, and its 
    76                        uid will be used automatically. 
    77                        If not set, a large value will be used automatically. 
    78                        Implies -d | --dousers. 
    79  
    80   -g | --gidmin gid    Only adds groups whose gid is greater than or equal to 
    81                        gid. You can pass a groupname there as well, and its 
    82                        gid will be used automatically. 
    83                        If not set, 0 will be used automatically. 
    84                        Implies -D | --dogroups. 
    85  
    86   -G | --gidmax gid    Only adds groups whose gid is lesser than or equal to 
    87                        gid. You can pass a groupname there as well, and its 
    88                        gid will be used automatically. 
    89                        If not set, a large value will be used automatically. 
    90                        Implies -D | --dogroups. 
    91  
    92 examples : 
    93  
    94   $ pkturnkey --dousers --uidmin jerome 
    95  
    96   Will simulate the initialization of PyKota's database will all existing 
    97   printers and print accounts for all users whose uid is greater than 
    98   or equal to jerome's one. Won't manage any users group. 
    99  
    100   To REALLY initialize the database instead of simulating it, please 
    101   use the -f | --force command line switch. 
    102  
    103   You can limit the initialization to only a subset of the existing 
    104   printers, by passing their names at the end of the command line.
