279 
280  edpykota [options] group1 group2 ... groupN
281
282options :
283
284  -v | --version       Prints edpykota's version number then exits.
285  -h | --help          Prints this message then exits.
286 
287  -a | --add           Adds users and/or printers if they don't
288                       exist on the Quota Storage Server.
289                       
290  -d | --delete        Deletes users/groups from the quota storage.
291                       Printers are never deleted.
292                       
293  -c | --charge p[,j]  Sets the price per page and per job to charge
294                       for a particular printer. Job price is optional.
295                       If both are to be set, separate them with a comma.
296                       Floating point values are allowed.
297 
298  -i | --ingroups g1[,g2...]  Puts the users into each of the groups
299                              listed, separated by commas. The groups
300                              must already exist in the Quota Storage.
301 
302  -u | --users         Edit users print quotas, this is the default.
303 
304  -P | --printer p     Edit quotas on printer p only. Actually p can
305                       use wildcards characters to select only
306                       some printers. The default value is *, meaning
307                       all printers.
308                       You can specify several names or wildcards,
309                       by separating them with commas.
310 
311  -G | --pgroups pg1[,pg2...] Adds the printer(s) to the printer groups
312                       pg1, pg2, etc... which must already exist.
313                       A printer group is just like a normal printer,
314                       only that it is usually unknown from the printing
315                       system. Create printer groups exactly the same
316                       way that you create printers, then add other
317                       printers to them with this option.
318                       Accounting is done on a printer and on all
319                       the printer groups it belongs to, quota checking
320                       is done on a printer and on all the printer groups
321                       it belongs to.
322 
323  -g | --groups        Edit users groups print quotas instead of users.
324                         
325  -p | --prototype u|g Uses user u or group g as a prototype to set
326                       print quotas
327                       
328  -n | --noquota       Doesn't set a quota but only does accounting.
329 
330  -r | --reset         Resets the printed page counter for the user
331                       or group to zero. The life time page counter
332                       is kept unchanged.
333                       
334  -l | --limitby l     Choose if the user/group is limited in printing                     
335                       by its account balance or by its page quota.
336                       The default value is 'quota'. Allowed values
337                       are 'quota' 'balance' 'quota-then-balance' and
338                       'balance-then-quota'.
339                       WARNING : quota-then-balance and balance-then-quota
340                       are not yet implemented.
341                       
342  -b | --balance b     Sets the user's account balance to b.                     
343                       Account balance may be increase or decreased
344                       if b is prefixed with + or -.
345                       WARNING : when decreasing account balance,
346                       the total paid so far by the user is decreased
347                       too.
348                       Groups don't have a real balance, but the
349                       sum of their users' account balance.
350                       
351  -S | --softlimit sl  Sets the quota soft limit to sl pages.                       
352 
353  -H | --hardlimit hl  Sets the quota hard limit to hl pages.
354 
355  user1 through userN and group1 through groupN can use wildcards
356  if the --add option is not set.
357 
358examples :                             
359
360  $ edpykota --add -p jerome john paul george ringo/ringo@example.com
361 
362  This will add users john, paul, george and ringo to the quota
363  database, and set their print quotas to the same values than user
364  jerome. User jerome must already exist.
365  User ringo's email address will also be set to 'ringo@example.com'
366 
367  $ edpykota --printer lp -S 50 -H 60 jerome
368 
369  This will set jerome's print quota on the lp printer to a soft limit
370  of 50 pages, and a hard limit of 60 pages. If either user jerome or
371  printer lp doesn't exist on the Quota Storage Server then nothing is done.
372
373  $ edpykota --add --printer lp --ingroups coders,it -S 50 -H 60 jerome
374 
375  Same as above, but if either user jerome or printer lp doesn't exist
376  on the Quota Storage Server they are automatically added. Also
377  user jerome is put into the groups "coders" and "it" which must
378  already exist in the Quota Storage.
379           
380  $ edpykota -g -S 500 -H 550 financial support           
381 
382  This will set print quota soft limit to 500 pages and hard limit
383  to 550 pages for groups financial and support on all printers.
384 
385  $ edpykota --reset jerome "jo*"
386 
387  This will reset jerome's page counter to zero on all printers, as
388  well as every user whose name begins with 'jo'.
389  Their life time page counter on each printer will be kept unchanged.
390 
391  $ edpykota --printer hpcolor --noquota jerome
392 
393  This will tell PyKota to not limit jerome when printing on the
394  hpcolor printer. All his jobs will be allowed on this printer, but
395  accounting of the pages he prints will still be kept.
396  Print Quotas for jerome on other printers are unchanged.
397 
398  $ edpykota --limitby balance jerome
399 
400  This will tell PyKota to limit jerome by his account's balance
401  when printing.
402 
403  $ edpykota --balance +10.0 jerome
404 
405  This will increase jerome's account balance by 10.0 (in your
406  own currency). You can decrease the account balance with a
407  dash prefix, and set it to a fixed amount with no prefix.
408 
409  $ edpykota --delete jerome rachel
410 
411  This will completely delete jerome and rachel from the Quota Storage
412  database. All their quotas and jobs will be deleted too.
413 
414  $ edpykota --printer lp --charge 0.1
415 
416  This will set the page price for printer lp to 0.1. Job price
417  will not be changed.
418 
419  $ edpykota --printer hplj1,hplj2 --pgroups Laser,HP
420 
421  This will put printers hplj1 and hplj2 in printers groups Laser and HP.
422  When printing either on hplj1 or hplj2, print quota will also be
423  checked and accounted for on virtual printers Laser and HP.
