22PyKota NEWS :
23       
24    - 1.23alpha20 :
25   
26        - Added the overwrite_jobticket directive. See pykota.conf.sample
27          for how to use it.
28         
29    - 1.23alpha19 :
30   
31        - Fixed an LDAP filtering problem when managing billing codes.
32       
33        - Added the unknown_billingcode directive. See pykota.conf.sample
34          for how to use it.
35       
36    - 1.23alpha18 :
37     
38        - Added the dump_bfd.php contribution.
39       
40        - Several fixes in the internal PJL accounter.
41       
42        - Now autopykota doesn't create unneeded print quota entries anymore.
43       
44        - Increased the timeout in the PJL hardware accounting code to
45          accomodate some printers (HP5000 at least).
46         
47    - 1.23alpha17 :
48   
49        - pkpgcounter is now distributed separately only. This
50          means that people must now download and install pkpgcounter
51          v1.56 or higher prior to being able to run PyKota.
52         
53        - Removed all the autoconf/automake stuff which was outdated 
54          and confusing.
55         
56    - 1.23alpha16 :
57     
58        - Extracted the GPL blurb from all commands' help, and use
59          a static version only once. This saves space big time, and
60          eases future translations.
61         
62    - 1.23alpha15 :
63   
64        - pkbcodes now works with the PostgreSQL backend.
65          NB : PLEASE RUN upgrade-to-1.23.sql AGAIN !!!
66       
67    - 1.23alpha14 :
68   
69        - Logs a warning when the user/group doesn't exist when running
70          edpykota.
71         
72    - 1.23alpha13 :
73   
74        - Minor fix for user groups because of latest database changes.
75       
76    - 1.23alpha12 :
77   
78        - Big database changes, use the migration scripts !
79       
80    - 1.23alpha11 :
81   
82        - Small fix to the PCL3/4/5 parser for some drivers.
83       
84    - 1.23alpha10 :
85   
86        - Fixed a bad exception name in cupspykota when parsing IPP messages.
87       
88        - Improved the IPP messages module : it can now generate IPP messages
89          in addition to parsing them.
90       
91    - 1.23alpha9 :   
92   
93        - The denyduplicates directive now accepts a command line as an
94          argument beside yes/no. The command is launched and must
95          print either ALLOW or DENY to its standard output. Then the
96          job gets allowed or denied by PyKota.
97          This will allow user interaction in the near future.
98         
99        - Introduced the new 'striptitle' directive to remove ugly prefixes
100          from print job's titles whenever a new print job is submitted.
101         
102        - Fixed internal SNMP accounter for printers which only have a life time
103          page counter, and not a volatile page counter.
104         
105    - 1.23alpha8 :
106   
107        - The data dumper can now summarize payments and history with the
108          help of the --sum command line option (or checkbox in the CGI).
109         
110        - The message used when the job's filename, title and options are
111          hidden because of the privacy directive is now translated at
112          retrieval time, instead of at saving time.
113         
114        - Minor fix in the LDAP backend code. 
115         
116    - 1.23alpha7 :
117   
118        - Improvements to the internal PJL and SNMP accounter : now should
119          support more printers and waste less time.
120         
121    - 1.23alpha6 :
122   
123        - The data dumper's start= and end= date filtering options now
124          accept a positive or negative offset to be added to the special
125          keywords 'yesterday', 'today', 'now', 'tomorrow'.
126          e.g. : dumpykota --data history start=yesterday-5 end=today
127         
128    - 1.23alpha5 :
129   
130        - The data dumper's start= and end= date filtering options now accept
131          the special keywords 'yesterday', 'today', 'now' and 'tomorrow'.
132         
133    - 1.23alpha4 :
134   
135        - The data dumper now accept start= and end= to specify the starting
136          and ending dates to dump the history.
137         
138    - 1.23alpha3 :
139   
140        - The destination link for the logo used in CGI scripts is
141          configurable.
142         
143        - Data dumper improved : it's faster and now datas are correctly
144          escaped.
145       
146        - The URL to the logo displayed in the CGI scripts is configurable.
147       
148    - 1.23alpha2 :
149   
150        - Fixed edpykota --prototype with balance.

156   
157        - Sets current username to the user CUPS runs as instead of "root"
158          when printing test pages from CUPS' web interface (because
159          the username is empty in this case).
160         
161        - Fix for strange values in job-originating-hostname
162       
163    - 1.22 :
164   
165        - Big improvements to the documentation.

217        - Allows pkbanner to accept more info to display on its
218          command line.
219         
220    - 1.22alpha3 :
221   
222        - Fixes some case related problems with some LDAP backends.
223       
224        - Fixes some problem for printers which directly go from
225          "idle" to "warmup" and never to "printing" before
226          returning to "idle".
227         
228        - Some permissions settings may have prevented cupspykota
229          from parsing cupsd.conf, this is now fixed.
230         
231    - 1.22alpha2 :
232   
233        - Introduction of the web enabled print quote generator.
234       
235        - Fixed a potential race condition when several backend
236          wrappers were present in CUPS' backend directory.
237         
238        - Fixed dumpykota's output in CUPS' page_log format to better

240         
241    - 1.22alpha1 :
242   
243        - Import into Subversion.
244

266    - 1.21alpha27 :
267   
268        - Allows software() (no arguments) to the software accounting
269          directive. This saves a lot of CPU since the job is not
270          parsed again : the precomputed size is used directly in this
271          case.
272         
273        - epykota's --prototype option now works fine with accounts
274          limited by balance.
275         
276    - 1.21alpha26 :
277   
278        - Fixed the handling of the 'maxdenybanners' directive.
279       
280        - Introduced the 'denyduplicates' directive.

285   
286        - The job's size is now always precomputed, even when
287          'enforcement' is not set to 'strict'.
288         
289        - Introduction of the new 'trustjobsize' configuration directive
290          to workaround some problematic printers. See the sample
291          configuration file for details.
292         
293    - 1.21alpha24 :
294   
295        - Big database structure changes. An upgrade script
296          is now included for PostgreSQL. LDAP users may just
297          want to copy the new schema in place.
298         
299        - edpykota now recognizes the -o | --overcharge command line
300          option to set an overcharging or undercharging factor
301          on each print job's cost for a particular user.
302         
303        - repykota's output format has changed an is not limited to 
304          80 characters wide anymore. People who used to parse
305          repykota's output in their own tools are strongly advised
306          to parse dumpykota's output instead.
307         
308        - Introduction of the new 'maxdenybanners' configuration directive
309          to allow up to N (the directive's value) deny banners to be
310          printed even if the print account is forbidden to print.
311         
312        - Better detection of the number of copies in the PostScript parser.
313       
314    - 1.21alpha23 :
315   
316        - Traditional Chinese translation added.
317   
318        - Several fixes and performance improvements with the LDAP backend.
319       
320    - 1.21alpha22 :
321   
322        - edpykota's --delete command line option doesn't consider
323          '*' to be the default argument anymore :-)
324         
325    - 1.21alpha21 :
326   
327        - dumpykota.cgi can now be run as a normal user as opposed to
328          a PyKota administrator. No read access to pykotadmin.conf is
329          necessary anymore. This CGI scripts now honors the REMOTE_USER
330          environment variable just like printquota.cgi does, see
331          the file cgi-bin/README for details.
332          The command line tool dumpykota must still be run by a PyKota
333          administrator.
334         
335        - Fix exception's name error due to a change in recent versions
336          of PygreSQL.   
337         
338    - 1.21alpha20 :
339         
340        - Big bug fix wrt the datelimit field which was never reset.
341         
342    - 1.21alpha19 :
343   
344        - Introduction of the new dumpykota.cgi CGI script, which
345          allows third party tools like phpPrintAnalyzer to be
346          interfaced in real time with PyKota. To use it you
347          may have to change your web server's configuration,
348          please see pykota/cgi-bin/README
349         
350    - 1.21alpha18 :
351   
352        - Now dumpykota can dump the job history into CUPS' page_log
353          format (even when the printing system is LPRng). This allows
354          people to use tools like PrintAnalyzer or phpPrintAnalyzer
355          (two completely different beasts) with PyKota.
356         
357    - 1.21alpha17 :
358     
359        - Fixed field type's name in XML dumps.
360       
361        - Now drops priviledges to user 'pykota' when launched as root
362          (directly or as a CUPS backend), if such an user exists.
363         
364        - Fixed PCL3/4/5 parser for some drivers' output.
365       
366    - 1.21alpha16 :
367   
368        - fixed several recently introduced bugs in LDAP backend code,
369          thanks to Matt Hyclak.
370         
371    - 1.21alpha15 :
372     
373        - Normalized field names between LDAP and PostgreSQL backends
374          in dumpykota's output.
375         
376        - dumpykota filtering capabilities are now supported within
377          the LDAP backend too.
378         
379    - 1.21alpha14 :
380   
381        - dumpykota now supports extended filtering possibilities
382          with the PostgreSQL backend (LDAP support will come soon).
383         
384    - 1.21alpha13 :
385   
386        - Added a --debug command line option to pkpgcounter, so
387          that people may see what really happens, and what will
388          be available in the future :-)
389         
390    - 1.21alpha12 :
391   
392        - Fixed a bug with non standard pkbanner command lines.
393       
394        - Now logs as errors the differences between precomputed and
395          computed job sizes. **CUPS only for now**
396         
397    - 1.21alpha11 :
398   
399        - Now user and group print quota entries can be stored directly
400          below the user or group with the LDAP backend, using them
401          as branches. Thanks to Stefan Wold for the patch.
402          See the sample configuration file for details.
403         
404        - TLS is now supported with the LDAP backend. Thanks to Stefan
405          Wold for the patch.
406          See the sample configuration file for details.
407         
408        - edpkota now accepts the -U | --used value command line argument
409          to preset the page counters to an initial value. Thanks to
410          Wilson Roberto Afonso and Matt Hyclak for the patch.
411         
412    - 1.21alpha10 :
413   
414        - Now automatically reconnects up to three times if the LDAP server
415          returned an error, possibly due to a timeout.
416         
417    - 1.21alpha9 :
418   
419        - Now searches the configuration files in 'pykota' system user's
420          home directory. The 'pykota' system user and group have
421          to be created by the system administrator, and given
422          sufficient permissions to PyKota's configuration files.
423         
424    - 1.21alpha8 :
425   
426        - Added the new reject_unknown directive to reject the
427          creation of user or groups which are unknown to the system.

466         
467    - 1.21alpha1 :
468   
469        - added an IPP messages miniparser. Extraction of the client
470          hostname is now considered to be fiable, at least until
471          the CUPS developpers change something...
472       
473    - 1.20 :
474   
475        - Version number changed.
476

486          to pykota.conf, to hide jobs' title, filename and options
487          in the history.
488         
489        - Minor changes in the debian directory.
490       
491    - 1.20alpha27 :
492

505       
506        - Fix for incorrect locale setting when starting.
507       
508    - 1.20alpha25 :
509   
510        - pkprinters allows --list to normal users, but require user
511          to be a PyKota administrator when another command line
512          option is used.
513         
514        - pkhint doesn't use absolute path to search for helper commands
515          anymore.
516         
517        - Spanish translation ready for 1.20.   
518       
519    - 1.20alpha24 :
520   
521        - Now warnpykota only warns users limited by balance once.
522       
523        - Now warnpykota only warns users who have ever printed,
524          to not cause confusion to users who have just opened
525          their account.
526       
527        - Prepared help messages for translations.
528       
529    - 1.20alpha23 :
530   
531        - Add workaround for locale problem.
532       
533    - 1.20alpha22 :
534   
535        - Hopefully final fix for data encoding charset.
536       
537        - edpykota now refuse to work if the user is not a PyKota admin.
538       
539        - Fixes a recently introduced bug with users groups and PostgreSQL.
540       
541    - 1.20alpha21 :
542   
543        - Now dumpykota refuses to launch if the current user is not
544          a PyKota administrator (a PyKota administrator is an user
545          allowed to read the pykotadmin.conf file).
546         
547        - Now any PyKota administrator can use repykota and warnpykota
548          with additionnal arguments, not only the root user.
549         
550        - Improved documentation a bit.
551       
552    - 1.20alpha20 :
553   
554        - Reduced delay in internal SNMP and PJL_over_TCP handlers
555          from 2 to 1 second.
556       
557        - dumpykota can now output XML.
558       
559    - 1.20alpha19 :
560   
561        - Improved user groups and user groups quotas dumps in dumpykota.
562       
563        - Finished implementation of LDAP support in dumpykota.
564       
565        - The md5 sum of the job's datas is now available as an
566          hexadecimal digest in the PYKOTAMD5SUM environment variable.
567         
568        - The description, filename, title, and options fields
569          are now stored as UTF-8 strings in both LDAP and PostgreSQL.
570          Proper charset is used during extraction from the database.
571         
572    - 1.20alpha18 :
573   
574        - Experimental autopykota command to initialize user
575          account and quota entries on first print while not
576          resetting the balance value if not needed.
577         
578        - Added the new "winbind_separator" directive to strip
579          out the Samba/Winbind domain name while printing if
580          needed (Off by default).
581         
582    - 1.20alpha17 :
583   
584        - Added --hardreset command line option to edpykota.
585       
586        - Fixed problem with accented chars in title, filename
587          or options and LDAP backend.
588         
589    - 1.20alpha16 :
590   
591        - Internal handling of socket based PJL queries over
592          port tcp/9100 is now available with the magic
593          'pjl' value in the hardware accounter.
594         
595    - 1.20alpha15 :
596   
597        - LDAP pykotaAccountBalance objects were always created
598          attached to the pykotaUser objects. This is now
599          fixed and the value of balancebase in pykota.conf
600          is now correctly used.
601         
602    - 1.20alpha14 :
603   
604        - Belgian translations added (copy of the french ones).
605       
606        - External hardware accounter now loops until
607          a result can be read correctly.
608         
609        - pkhint now suggest the internal snmp handling instead
610          of the external one.
611         
612    - 1.20alpha13 :
613     
614        - Hardware accounter now accepts the special
615          'snmp' value, meaning ALL is done from main code
616          without launching any subprocess.
617          You need the http://pysnmp.sf.net Python module
618          for this to work (tested with v3.4.2)
619         
620        - Increased delay between two loops iterations 
621          to 2 seconds in waitprinter.sh to diminish
622          CPU load.
623         
624    - 1.20alpha12 :
625   
626        - waitprinter.sh rewritten from scratch to wait
627          for printer status stabilization.
628       
629    - 1.20alpha11 :
630   
631        - Generic data dumper 'dumpykota' introduced.
632          Works only with PostgreSQL backend for now.
633         
634    - 1.20alpha10 :
635   
636        - Added fix for incorrect job's size computation when
637          hardware accounting fails.
638         
639    - 1.20alpha9 :
640   
641        - Small fixes wrt subprocesses.
642       
643    - 1.20alpha8 :
644   
645        - Added full support of PCL3 : HP Deskjet printers are now
646          supported.
647       
648    - 1.20alpha7 :
649   
650        - First draft of PCL3GUI (Deskjet 640C for example) analyzer.
651          Needs more work, but no documentation is available.
652       
653    - 1.20alpha6 :
654     
655        - Improved mailandpopup.sh script.
656       
657        - Small fixes for LPRng.
658       
659        - Now exports PYKOTAPRINTERHOSTNAME for network printers'
660          hostname or IP address. Set to 'localhost' when not
661          meaningful.
662         
663        - Fixed issue with how mod_auth_ldap Apache modules
664          fills the REMOTE_USER environment variable.
665         
666        - Fixed a bug in LDAP user deletion code.
667       
668    - 1.20alpha5 :
669     
670        - Introduces the new configuration directive 'onaccountererror'
671          to specify what must be done whenever the software or
672          hardware accounter fails. Allowed values are 'continue' and
673          'stop' (default).
674         
675        - Minor fix in software accounter for a recently introduced
676          problem.
677         
678    - 1.20alpha4 :
679   
680        - Added support for more ghostscript devices in ESC/P2
681          analyzer : stcolor, st800, escp, escpc are now supported.
682         
683    - 1.20alpha3 :
684       
685        - Small improvement in PostScript parser to avoid being
686          fooled by a change in number of copies :
687          The user can't ask for 200 copies of page 1 and 1 copy
688          of page 2 to fool PyKota anymore :
689          this would have been accounted for as 1 copy only, but
690          now the maximum value seen is used.
691         
692        - Relax checks for PCL5 header to accomodate some strange
693          printer drivers.
694         
695        - Now hardware accounting method works like software
696          accounting method wrt the subprocess' output.
697         
698        - Hardware and Software accounting stop the print queue 
699          when the accounting subprocess didn't work. This will
700          be configurable in the near future.
701         
702    - 1.20alpha2 :
703   
704        - Now software accounting method reads accounter's
705          answer until a line with a single integer is
706          obtained or until all of its output has been read.
707          This should fix the problem some people have
708          when strange locale related messages are sent
709          when running subprocesses (Solaris only ?).
710         
711        - First version of ESC/P2 analyzer. Seems to work
712          ok at least with 'epson', 'epsonc', 'eps9mid'
713          and 'esp9high' ghostscript devices. Needs more
714          work to correctly analyze other devices.
715       
716    - 1.20alpha1 :
717   
718        - Fixed problem with number of copies in PCLXL parser.
719       
720        - Fixed problem with number of copies in PCL5 parser,
721          when number of copies was set outside of and before first
722          page.
723       
724        - Added workaround for number of copies directly set in
725          PostScript code.
726         
727        - Added german translation.
728       
729        - Fixed problem on first print for user group quota when
730          "enforcement: strict" is used.
731       
732        - Fixed interpolation problem in french translation.
733       
734    - 1.19 :
735   
736        - Updated existing translations.   
737       
738        - Added final Thai and Greek translations.
739       
740        - Minor last minute bug fixes.
741       
742    - 1.19beta :
743   
744        - LPRng support for both software and hardware accounting seems
745          to be OK.
746         
747        - Translation files fixed because of fuzzy matching problem. 
748       
749        - Fixed path to Swedish translation: 'sv' instead of 'se'.
750       
751        - Added first draft of Thai translation.
752       
753        - Fixed some minor bugs with Pychecker.
754       
755    - 1.19alpha35 :
756   
757        - Generic PDL analyzer now supports Binary PostScript documents
758          in addition to DSC compliant ones.
759       
760    - 1.19alpha34 :
761   
762        - LPRng support : software accounting seems to work fine,
763          but hardware accounting doesn't work yet.
764   
765    - 1.19alpha33 :
766   
767        - pykosd now accepts command line arguments. Enjoy !
768          NB : due to a bug in xosd, you need xosd version 2.2.8
769          or higher if you don't use the default C locale.
770         
771    - 1.19alpha32 :
772   
773        - Early (not working) version of the LPRng support rewrite.
774       
775        - Saner default configuration file.
776       
777    - 1.19alpha31 :
778   
779        - Fixed a double Python2.1 incompatibility with newer versions,
780          which prevented the PCL5 and the PCLXL parsers to work with
781          this older version of Python.
782         
783    - 1.19alpha30 :
784   
785        - Introduction of preliminary version of the pykosd command
786       
787        - Usernames, Groupnames and Printernames can now contain
788          ANY character, expected '/' and '@'.
789       
790        - Integrated most of the Debian work from Sergio
791          Gonz�z Gonz�z
792         
793    - 1.19alpha29 :
794   
795        - PCLXL parser should now correctly handle number of
796          copies set for each page.
797         
798        - Added testsuite for generic PDL analyzer.
799       
800        - Typo fixed in PCLXL parser.
801       
802        - Correctly dispatches error messages depending on the
803          situation : tools which can be run interactively will
804          ALWAYS output their logs to stderr, excepted for
805          their DEBUG messages, for which the "logger:"
806          directive as set in pykota.conf will be honored.
807          Tools which can't be run interactively will ALWAYS
808          honor the "logger:" directive as set in pykota.conf
809         
810    - 1.19alpha28 :
811   
812        - The description field for printers can now be set,
813          and is displayed in reports.
814         
815        - Fixed a small problem in SQL backend code.
816         
817        - Improved pkhint
818       
819        - First working PCL6 (aka PCLXL) parser !
820          Doesn't handle copies yet.
821       
822    - 1.19alpha27 :
823   
824        - Additionnal 10% speed increase in PCL5 parser for GhostScript
825          generated files (untested yet with other PCL files).
826         
827        - Reintroduced the use of mmap in PCL5 parser : this speedups
828          PCL5 parsing by almost 4 times.
829          This 4x with the 3x below give us in fact a twelvefold increase
830          in performance for PCL5 parsing !
831         
832        - The Python accelerator Psyco is now used if available
833          in the generic PDL parser : it speedups PCL5 parsing by
834          almost three times automagically.
835         
836    - 1.19alpha26 :
837   
838        - Fixed PCL5 parser according to the sources of rastertohp.
839       
840        - Fixed number of copies handling in PCL5 parser : the number
841          of copies could vary from page to page.
842         
843        - Added more debug information to PCLXL parser. 
844       
845    - 1.19alpha25 :
846   
847        - Added new "description" field to printers in both
848          PostgreSQL and LDAP. No code to handle this yet.
849         
850        - Reversed the fix for power save mode in printers : 
851          no paper or tray open would have caused people to
852          be undercharged.
853         
854        - Preliminary version of MySQL initialization script.
855         
856    - 1.19alpha24 :
857   
858        - Native PDF parsing code now works perfectly with
859          Python 2.1 and above, and is way faster than before.
860          GhostScript is not used anymore to convert PDF to PS,
861          because PDF is parsed directly.
862         
863    - 1.19alpha23 :
864   
865        - Fixed waitprinter.sh wrt PowerSave mode and some
866          printers. Thanks to Ryan Suarez.
867       
868        - Smart PDL analyzer now recognizes PDF too : two
869          PDF parsing methods are used : a native one which
870          is very fast but requires Python 2.3 or above, and
871          a slower one which uses Ghostscript. PyKota detects
872          automatically which method to use depending on your
873          version of Python.
874       
875        - All tracebacks now include PyKota's version number.
876         
877    - 1.19alpha22 :
878   
879        - Ensures that the file pointer for job's data is
880          reset to the start of the job's datas after the
881          job's size pre-computation phase.
882         
883        - Improved PostScript detection code for bad drivers
884          which don't correctly switch languages between PJL
885          and PS.
886       
887        - Even better debugging code.
888       
889    - 1.19alpha21 :
890   
891        - Additionnal check.
892       
893    - 1.19alpha20 :
894   
895        - More complete logging messages wrt accounters.
896       
897        - Now catches early failures occuring when the configuration
898          files are parsed.
899       
900    - 1.19alpha19 :
901   
902        - Fixed over-verbose exits when displaying help
903          or version.
904         
905        - Extended some PATH in the shell scripts 
906       
907        - Deleting an user now also deletes his payments history.
908       
909        - Doesn't explicitely ignore SIGCHLD anymore. This seems to
910          cause problems.
911
912    - 1.19alpha18 :
913   
914        - History of payments is now stored in the database, and
915          updated each time an user's balance is modified with
916          edpykota --balance. This history represents each time
917          the user was given some positive or negative credit,
918          but doesn't reflect price paid for jobs, which appear
919          in the jobs history instead.
920         
921        - Jobs history web reports now include the job's size in
922          bytes. Also columns were reordered to render the report
923          more easily readable.
924         
925    - 1.19alpha17 :
926   
927        - Mysterious bug (program exited unexpectedly without leaving
928          any log message) which occured once in a while when
929          cancelling jobs should be fixed now.
930         
931        - New 'crashrecipient' directive. Disabled by 
932          default. See sample configuration file to see how
933          to activate it. It is suggested that you activate it.
934         
935        - New PYKOTAJOBSIZEBYTES environment variable exported, 
936          which contains the job's size in bytes. Empty jobs
937          are now denied. This value is now stored in the job
938          history (but not yet displayed from the web interface)
939         
940        - Preliminary work on payments storage : the PostgreSQL 
941          and LDAP schemas should be OK now, but no code is written
942          yet to support this functionnality.
943         
944    - 1.19alpha16 :
945   
946        - the newuser and newgroup LDAP specific directives now accept
947          a second parameter to attach(), "fail" or "warn". If no entry
948          is found to attach PyKota attributes to, and "fail" was used,
949          then action is aborted and program exits in error. If "warn"
950          is used, a new entry is created but a warning message is logged.
951         
952        - The job's originating hostname is now stored in the database,
953          and exported as PYKOTAJOBORIGINATINGHOSTNAME in the environment.
954       
955    - 1.19alpha15 :
956   
957        - The old pykota filter is now removed. This means that
958          currently PyKota doesn't support LPRng anymore, but
959          LPRng support will be re-added, improved, in the near future.
960         
961    - 1.19alpha14 :
962   
963        - PYKOTAPRECOMPUTEDJOBSIZE and PYKOTAPRECOMPUTEDJOBPRICE
964          are now exported as environment variables.
965         
966        - Heavy CPU usage is now completely fixed it seems, by
967          introducing some 0.01 second sleeping when nothing to do.
968         
969        - Pre-computation of the job's size is now only
970          done when enforcement is "STRICT", this saves
971          CPU for people who don't want to use this new
972          feature.
973         
974        - New 'enforcement' directive which accepts either
975          STRICT or LAXIST. See sample configuration file
976          for details.
977         
978    - 1.19alpha13 :
979   
980        - Get back to an old version of the polling loop which
981          worked fine, but non-optimally. Will be optimized
982          as time permits.
983         
984    - 1.19alpha12 :
985   
986        - Job's size is now precomputed unconditionnally using
987          the generic PDL analyzer.
988          NB : This value is not yet used to pre-allow/deny the
989          job.
990       
991    - 1.19alpha11 :
992   
993        - The pykota filter is now completely deprecated and
994          can't be used anymore. LPRng users MUST download
995          an older version of PyKota. CUPS users MUST use
996          cupspykota. Better support for LPRng will come
997          in the near future.
998         
999    - 1.19alpha10 :
1000   
1001        - pykotme now uses generic PDL Analyzer directly instead
1002          of spawning a new process.
1003         
1004        - Improvements to generic PDL Analyzer.
1005       
1006        - 25% Speedup in PCL parser. Getting more of the Python version
1007          will probably be difficult, since the completely table driven
1008          parser I wrote is slower than the original algorithm. Then,
1009          the original algorithm is still used for now.
1010          Probable that more speed could be achieved using mmap, at the
1011          expense of severe memory consumption.
1012       
1013        - configuration simplifications : the "accounter" directive's
1014          'hardware' arguments now accepts what was in the "requester"
1015          directive as it's content. The "requester" directive is not
1016          supported anymore. See sample configuration file for details.
1017       
1018    - 1.19alpha9 :
1019       
1020        - pkpgcounter is now just a wrapper around the PDLAnalyzer class
1021       
1022        - pykotaOptions LDAP attribute now accepts non-ascii characters
1023          too.
1024         
1025        - First try at cupspykota main loop rewrite
1026       
1027    - 1.19alpha8 :
1028   
1029        - 'querying' accounting method is now called 'hardware'
1030       
1031        - 'external' accounting method is now called 'software'
1032       
1033        - 'stupid' accounting method doesn't exist anymore
1034       
1035        - 'snmp' requester doesn't exist anymore
1036       
1037        - code simplifications in external requester
1038       
1039    - 1.19alpha7 :
1040     
1041        - Database schema change (both LDAP and PostgreSQL) to
1042          allow storage of the job-originating-hostname attribute.
1043          An SQL upgrade script is present. The code is not yet
1044          capable of setting/retrieving this attribute. Support
1045          for this functionnality will be added in the future.
1046         
1047    - 1.19alpha6 :
1048   
1049        - problems connecting to SMTP servers are now catched.
1050       
1051        - pykotme now uses pkpgcounter to compute the size of the
1052          job. This modification adds PCL5 and soon PCLXL (PCL6)
1053          support. You can now get quotes for PCL in addition to
1054          PostScript.
1055         
1056        - pkpgcounter now includes first try at PCLXL parser. 
1057          It is currently disabled until it's finished.
1058         
1059    - 1.19alpha5 :
1060   
1061        - cupspykota polling loop fix for MacOSX (at least)
1062       
1063        - logging subsystem now logs PID too, to ease diagnosing
1064          problems under heavy load.
1065         
1066        - pkpgcounter enhancements.
1067       
1068        - pkprinters --skipexisting now tells pkprinters to not
1069          modify existing printers when --add is used.
1070          pkprinters logs a warning message whenever --add is
1071          used and a printer already exists.
1072         
1073        - LDAP schema now allows accented chars in pykotaFileName
1074          and pykotaTitle attributes.
1075       
1076    - 1.19alpha4 :
1077   
1078        - a bad copy&paste prevented pkpgcounter to work at all, this
1079          is now fixed.
1080         
1081        - improved PCL support in pkpgcounter, with the use of
1082          HP PCL/PJL Reference Set
1083          PCL5 Printer Language Technical Quick Reference Guide
1084       
1085        - pkpgcounter now uses mmap to speed things up : duration
1086          is halved with the sample 87 pages PCL document I use for
1087          testing.
1088         
1089    - 1.19alpha3 :
1090   
1091        - pkprinters now accepts the --list command line argument
1092          to list informations about printers.
1093         
1094    - 1.19alpha2 :
1095   
1096        - pkpgcounter is now included as a smart external
1097          accounter which can handle both PostScript and PCL.
1098         
1099    - 1.19alpha1 :
1100   
1101        - PYKOTALIMITBY environment variable is now exported too.
1102       
1103        - Inclusion of Michele Baldessari's work on autotools.
1104       
1105    - 1.18 :
1106

1116       
1117        - Better tracebacks on error conditions
1118       
1119        - Improved translations
1120       
1121        - Improved documentation
1122       
1123    - 1.18alpha15 :
1124
1125        - waitprinter.sh replaced by a new and possibly faster
1126          and more powerful one.
1127   
1128        - Names can now begin with a digit.
1129       
1130        - Stability improvement for quotas set on printers groups.
1131       
1132    - 1.18alpha14 :
1133   
1134        - Catches more (all ?) problems with SMTP servers instead
1135          of breaking.
1136         
1137        - Italian translation added.
1138       
1139    - 1.18alpha13 :
1140   
1141        - Pre and Post hooks are now available in the pykota
1142          filter as well.
1143         
1144        - The pykota filter doesn't check last user's quota
1145          anymore when delayed hardware accounting is used :
1146          this will be done anyway the next time the last
1147          user will print again. This saves some database
1148          queries which are unneeded.
1149       
1150    - 1.18alpha12 :
1151   
1152        - Pre and Post hooks to external commands with many
1153          many environment variables available are useable
1154          from the cupspykota backend.
1155          See sample configuration file for details and help.
1156         
1157    - 1.18alpha11 :
1158   
1159        - Hopefully final fix wrt groups (users and printers)
1160       
1161    - 1.18alpha10 :
1162   
1163        - Fixed nested printer groups accounting.
1164       
1165        - Fixed user groups + printer groups problem.
1166       
1167    - 1.18alpha9 :
1168

1170       
1171        - Fix for empty user groups with LDAP.
1172       
1173        - Preliminary version of the snmpprinterstatus command added.
1174       
1175    - 1.18alpha8 :
1176   
1177        - Don't retrieve data when not needed.
1178          This avoids many database queries.
1179

1181   
1182        - New experimental ldapcache directive to improve
1183          LDAP caching.
1184

1191        - More complete email message headers. 
1192         
1193    - 1.18alpha5 :
1194   
1195        - Debian packaging specific files, contributed by
1196          Peter Hawkins are now included in the project's tree.
1197         
1198        - Preliminary work on future low-level LDAP caching to speed
1199          up modifications (at least).
1200         
1201    - 1.18alpha4 :
1202   
1203        - Applied some of the modifications suggested by
1204          Peter Hawkins, for better Debian integration.
1205          Most notably cupspykota, pykota, and the shell
1206          scripts are now installed into /usr/share/pykota
1207          instead of into /usr/bin
1208          BEWARE : double check that your symbolic link
1209          to cupspykota is correct, and that your pykota.conf
1210          file use correct path for the shell scripts like
1211          waitprinter.sh and al.
1212         
1213        - pkhint command added, to help in configuring correct
1214          accounting method for PyKota.

1250          added to the documentation. Doesn't yet document v1.16
1251          though.
1252       
1253        - Portuguese Portuguese translation replaces Brazilian
1254          Portuguese Translation. Brazilian portuguese
1255          translation is still available under the 'br' locale.
1256       
1257    - 1.16beta3 :
1258

1262       
1263    - 1.16beta2 :
1264   
1265        - Small fix for job cancelling code while job already
1266          printing in CUPS backend.
1267         
1268        - Big fix wrt printing policies for unknown users. 
1269       
1270    - 1.16beta1 :
1271   
1272        - Manpages upgraded.
1273       
1274    - 1.16alpha26 :
1275   
1276        - Job price is now computed like this :
1277       
1278          SUM((NbPages * PricePerPage) + PricePerJob)
1279         
1280          For current printer and all the printers groups it is
1281          a member of, if any.
1282         
1283          This may be difficult to grasp, but offers unprecedented
1284          flexibility.
1285         
1286    - 1.16alpha25 :
1287   
1288        - Email address can be set at user creation time,

1300          automatically add printers on first print.
1301       
1302    - 1.16alpha23 :
1303   
1304        - Fixed potential accuracy problem if a user printed on
1305          several printers at the very same time.
1306       
1307    - 1.16alpha22 :
1308   
1309        - edpykota now allows adding printers to printer groups
1310

1312   
1313        - Allows the dot in user and printer names.
1314       
1315        - Printer groups are now cached too.
1316       
1317    - 1.16alpha20 :

1321    - 1.16alpha19 :
1322     
1323        - Fixed a bug in PostgreSQL backend's code.
1324       
1325    - 1.16alpha18 :
1326   
1327        - Initial code for printer groups support. Printer groups have
1328          to be added with external tools like psql or gq for example.
1329          Printer groups seems to work fine with users. Untested with user
1330          groups for now.
1331
1332        - Several minor visual problems fixed in reports.
1333       
1334        - Fixed a bug in LDAP date handling.
1335       
1336        - Fix for LDAP problem with some combination of OpenLDAP + Python-LDAP
1337          + some particular settings.
1338         
1339        - mailandpopup.sh shell script added. See sample configuration file
1340          for details.
1341       
1342        - Several environment variables are now exported when executing
1343          external commands (accounters, requesters, mailers) :
1344           
1345            PYKOTAUSERNAME => user who is printing
1346            PYKOTAPRINTERNAME => printer on which the job is being sent
1347            PYKOTATITLE => Job's title
1348            PYKOTAFILENAME => Job's filename
1349            PYKOTACOPIES => number of copies asked
1350            PYKOTAOPTIONS => print command options (-o with CUPS)

1361          have nice looking and useful web based reports (in the future).
1362       
1363        - Added utolower configuration option to convert all usernames
1364          to lowercase during printing.
1365         
1366    - 1.15alpha15 :
1367   
1368        - Now includes the papwaitprinter.sh shell script to wait for
1369          AppleTalk enabled printers.
1370         
1371    - 1.16alpha14 :
1372   
1373        - Now printing on a printer not defined in the Quota Storage,
1374          results in the job being cancelled or stopped, depending
1375          on the printing system.
1376         
1377    - 1.16alpha13 :
1378   
1379        - Small bugfix wrt Python v2.1
1380       
1381        - If username is an empty string, user root is assumed.
1382       
1383        - 'postgresql' is not recognized anymore as a storage backend,
1384          you have to use 'pgstorage' instead. 'postgresql' used to
1385          be supported for compatibility with very old PyKota versions,
1386          this is not the case anymore.
1387         
1388    - 1.16alpha12 :
1389   
1390        - Job price added to job history, to keep accounting correct
1391          if a printer price per page or per job is modified and the
1392          history is not reset : the history would have given a false
1393          amount of money charged before the printer's prices were
1394          modified, this addition solves the problem.
1395         
1396    - 1.16alpha11 :
1397   
1398        - Some preliminary modifications to the database structure for
1399          PostgreSQL and OpenLDAP. A script to upgrade a PostgreSQL
1400          database is now provided. LDAP attributes now support
1401          eq, pres and sub indexes.
1402         
1403        - Job history now contains additional informations : 
1404          number of copies, filename, title and print options.
1405         
1406    - 1.16alpha10 :
1407       
1408        - Some modifications done to external policy handling.
1409          See sample configuration file for details.
1410   
1411        - Spanish translation added.
1412       
1413    - 1.16alpha9 :
1414   
1415        - mailto can be set to external(...) to warn users above
1416          quota with any command of your choice (e.g. linpopup).
1417          Several parameters are available, see sample configuration
1418          file for details.
1419         
1420    - 1.16alpha8 :
1421   
1422        - Now cupspykota transmits SIGTERMS to the original 
1423          backend when the user deletes a job being processed.

1429   
1430        - The CUPS backend is now fully functionnal (it seems).
1431       
1432        - From now on, the use of the pykota filter with CUPS
1433          is deprecated. The pykota filter still has to be
1434          used with LPRng though.
1435       
1436    - 1.16alpha6 :
1437   
1438        - Bug fixed : when edpykota was used to add a printer
1439          with no user or group name, a bad user/group name "*" was
1440          added to the database.
1441         
1442    - 1.16alpha5 :
1443   
1444        - New CUPS backend supports device enumeration !
1445          This means that NO manual CUPS configuration has to
1446          be done. All can now be done from CUPS web interface.
1447       
1448    - 1.16alpha4 :
1449   
1450        - New CUPS backend added.
1451

1471   
1472        - Command line tools now accept multiple printer
1473          names or wildcards, separated with commas.
1474         
1475    - 1.15alpha9 :
1476   
1477        - External policy can be used to auto-add unknown users
1478          and any other interesting things you may want to do.
1479          WARNING : You can't auto-add printers for now.
1480          They have to be created manually before.
1481          Look at sample configuration file for examples.
1482         
1483    - 1.15alpha8 :
1484   
1485        - Job history can be disabled if needed.
1486          This feature may be useful for people who use the LDAP
1487          backend and don't want their LDAP tree to grow out of
1488          control.
1489       
1490    - 1.15alpha7 :
1491   
1492        - More work done on caching wrt groups.
1493       
1494    - 1.15alpha6 :
1495   
1496        - Performance bottleneck with LDAP solved.
1497       
1498    - 1.15alpha5 :
1499   
1500        - Caching mechanism for all database queries.
1501
1502    - 1.15alpha4 :
1503   
1504        - Problem with Python 2.3 fixed. Needs some definitive
1505          modification.
1506         
1507    - 1.15alpha3 :
1508   
1509        - CGI script now tries to restrict view when the
1510          REMOTE_USER environment variable is set. This allows
1511          people to protect its use with .htaccess files.
1512          When unprotected, or if REMOTE_USER is 'root', then
1513          unrestricted access is granted.
1514          NB : REMOTE_USER is automatically set by the web server
1515          (e.g. Apache) when a page with restricted access is viewed.
1516         
1517    - 1.15alpha2 :
1518   
1519        - Better detection of LPRng.
1520       
1521        - Outputs a warning if printing system is unknown.
1522       
1523    - 1.15alpha1 :
1524   
1525        - Bug fix in SQL code.
1526       
1527    - 1.14 :
1528   
1529        - The PostgreSQL database connection is now always closed before
1530          exit. The LDAP database connection too, but it didn't suffer
1531          from the problem anyway, AFAICT.
1532       
1533    - 1.14beta2 :
1534   
1535        - An LDAP-specific configuration field was introduced, usermail.
1536          Use it to specify which LDAP attribute contains a valid email
1537          address for the user. See sample configuration file for
1538          details.
1539       
1540    - 1.14beta :
1541   
1542        - Two new LDAP-specific configuration fields were introduced,
1543          newuser and newgroup. Use them to specify if you want to add
1544          quota information to existing entries or elsewhere.
1545          See sample configuration file for details.
1546         
1547    - 1.14alpha9 :
1548   
1549        - Documentation improved.
1550       
1551        - pykotme now also prints the user's account balance value
1552          if the user is registered in the Quota Storage and his
1553          limiting factor is "balance".
1554         
1555    - 1.14alpha8 :
1556   
1557        - bin/waitprinter.sh is now included to wait for
1558          SNMP enabled printers to be idle again before
1559          asking for their internal page counter.
1560          See sample configuration file for details.
1561         
1562    - 1.14alpha7 :
1563   
1564        - edpykota now doesn't check if the user/group is above
1565          quota. The check is only done at print time. This
1566          prevents the sending of email messages when creating
1567          user quotas if quota is already reached at creation
1568          time.
1569         
1570    - 1.14alpha6 :
1571   
1572        - Configuration file split and moved to /etc/pykota/pykota.conf
1573          and /etc/pykota/pykotadmin.conf to prevent simple users to
1574          have Read/Write access to the Quota Database.
1575          Don't forget to :
1576         
1577                $ chmod 640 /etc/pykota/pykotadmin.conf
1578               
1579        - storageuser and storageuserpw configuration fields reintroduced
1580          for the same reason.
1581         
1582        - Code cleaning for future implementation of email addresses
1583          support in the PostgreSQL and LDAP backends.
1584         
1585    - 1.14alpha5 :
1586       
1587        - Big bug fixed when changing the prices for a printer
1588       
1589    - 1.14alpha4 :
1590   
1591        - When adding an user, the user itself and its account balance
1592          are now added in the same LDAP entry. Before they were added
1593          as two different LDAP entries.
1594         
1595    - 1.14alpha3 :
1596   
1597        - Email field added to PostgreSQL database. An upgrade script
1598          is included in initscripts/postgresql.
1599       
1600    - 1.14alpha2 :
1601   
1602        - Typo fixed when using the --prototype option to edpykota
1603       
1604    - 1.14alpha1 :
1605   
1606        - Poor man's treshold included : users with a low account
1607          balance (below 1.0 by default, configurable) are sent
1608          a warning message.
1609         
1610        - All warning messages to users are now configurable. 
1611          NB : Warning messages to the administrator are not.
1612       
1613    - 1.13 :
1614   
1615        - Some small fixes wrt group handling.
1616       
1617        - The whole module code was passed through PyChecker and
1618          several small code inconsistencies were fixed,
1619          as well as a bug in the groups code.
1620         
1621    - 1.13alpha1 :
1622   
1623        - Bug fix wrt LDAP.
1624       
1625    - 1.12 :
1626   
1627        - More complete test added in edpykota.
1628       
1629    - 1.12alpha2 :
1630   
1631        - The previous bug fix was incomplete. This is corrected.
1632       
1633    - 1.12alpha1 :
1634   
1635        - Small bug fix.
1636       
1637    - 1.11 :
1638   
1639        - Now includes the pykotme command line tool, to produce
1640          printing quotes for users.
1641         
1642    - 1.10 :
1643   
1644        - Bug fixed wrt quota reports when print limiting is by
1645          account balance.
1646         
1647    - 1.09 :
1648   
1649        - Translations finalized.
1650       
1651        - Manpages updated.
1652       
1653        - Installation documentation improved wrt LDAP support.
1654       
1655    - 1.09beta2 :
1656   
1657        - The CGI script for quota reports works again, and
1658          is much more powerful.
1659       
1660    - 1.09beta :
1661   
1662        - edpykota finalized
1663       
1664    - 1.09alpha2 :
1665   
1666        - LDAP schema modified a bit. Please upgrade.
1667       
1668        - LDAP backend works !
1669       
1670        - repykota and warnpykota allow the root user to pass
1671          users or groups names on the command line. Users
1672          and groups names may contain wildcards.
1673         
1674        - repykota and warnpykota only reports or warns the
1675          current user when launched by non-root users.
1676         
1677        - Minor bug fixes. 
1678   
1679    - 1.09alpha1 :
1680   
1681        - More work on LDAP storage backend. Many options
1682          were added to /etc/pykota.conf to give some
1683          hints to the LDAP storage backend.
1684         
1685        - Severe database access optimizations were done by
1686          rewriting most of the Quota Storage backends drivers.
1687     
1688    - 1.08 :
1689   
1690        - Major bug fix wrt LPRng support for remote jobs.
1691       
1692        - Major bug fix wrt increase/decrease account balances.
1693       
1694    - 1.08alpha8 :
1695   
1696        - Code refactoring.
1697       
1698        - A single user/password pair is used to connect
1699          to the database backend. The storageuser configuration
1700          field, and its associated passwords storageuserpw, are
1701          not used anymore.
1702         
1703        - You can now set PyKota in debug mode, see sample configuration 
1704          file for details.
1705          WARNING : only Quota Storage backend queries are logged in
1706          debug mode, for now.
1707       
1708    - 1.08alpha7 :
1709   
1710        - Very latest LDAP schema.
1711       
1712        - Code enhancement wrt easy pluggability of PyKota attributes
1713          and object classes into an existing LDAP directory.
1714       
1715    - 1.08alpha6 :
1716   
1717        - Minor bug corrections
1718       
1719        - More work on LDAP : new schema
1720       
1721    - 1.08alpha5 :
1722   
1723        - More good work on LDAP storage.
1724          repykota now works reasonably well with the sample LDAP directory.
1725       
1726    - 1.08alpha4 :
1727   
1728        - LDAP schema included.
1729          THIS IS JUST FOR PEOPLE TO DISCUSS ABOUT THIS.
1730          LDAP SUPPORT DOESN'T WORK YET, AND THE SCHEMA
1731          MAY CHANGE IN THE FUTURE. PLEASE TELL US
1732          WHAT YOU THINK ABOUT THIS SCHEMA ON THE
1733          MAILING LIST.
1734         
1735    - 1.08alpha3 :
1736   
1737        - External accounting methods were partly rewritten :
1738         
1739          - No more "broken pipe" should happen.
1740         
1741          - They now take care of the number of copies
1742            This may be unneeded though, if the postscript
1743            file already does this, because this would
1744            overcharge users (number of copies counted
1745            two times). NEEDS MORE TESTING.
1746           
1747          - The sample configuration file now contains 
1748            an external accounting method example which should
1749            work with all DSC compliant Postscript files.
1750           
1751        - Some small bugs were fixed.   
1752       
1753    - 1.08alpha2 :
1754   
1755        - Now works with net-snmp v5.0 and above.
1756          It already worked, but the sample configuration
1757          file didn't contain appropriate values...
1758       
1759    - 1.07 : Release of the Shame !
1760   
1761        - The external accounting methods driver was left out of
1762          the CVS tree. Nobody could use it since it wasn't included !
1763         
1764    - 1.06 :
1765   
1766        - Severe bug fixed : if you had a printer in
1767          power saving state which couldn't answer immediately,
1768          a bug was triggered.
1769          It was caused by a bad copy/paste which
1770          forgot to import a Python module at run time.
1771         
1772    - 1.05 :
1773   
1774        - External accounters are finally available !
1775          This means that you can plug any page accounting
1776          method you like by setting the appropriate
1777          'accounter' field in /etc/pykota.conf
1778          See the sample conf/pykota.conf.sample to
1779          learn how to do.
1780         
1781          NB : Both 'external' and 'stupid' accounting methods
1782               account a job size just before *this* job is
1783               sent to the printer.
1784               The original 'querying' method accounts a job
1785               size just before *the next* job is sent to
1786               the printer.
1787       
1788    - 1.05alpha3 :
1789   
1790        - A 'stupid' and unreliable accounting method was
1791          implemented to serve as an example on how to
1792          do this sort of things. This method only counts
1793          the 'showpage' statements in the input data.
1794          See sample configuration file for details.
1795          Pluggable accounting methods work, but I advise
1796          you TO NOT USE THIS ONE WHICH IS JUST AN EXAMPLE.
1797          It is not reliable enough to be used.
1798          Use the 'querying' accounting method instead.
1799         
1800    - 1.05alpha2 :
1801   
1802        - Pluggable accounting methods.
1803       
1804        - Better error handling.
1805       
1806    - 1.05alpha1 :
1807   
1808        - SECURITY file added to help improve PyKota's security.
1809       
1810        - Extracting the printer's internal page counter is now
1811          tried several times, waiting several seconds between
1812          two tries. This lets the time to warm up for some printers
1813          which don't answer when they are sleeping (my Apple
1814          LaserWriter 16/600 PS is in this case, maybe others too)
1815         
1816        - Small display bug fixed in repykota
1817         
1818    - 1.04 :
1819   
1820        - Default print policy for users/groups unknown from
1821          the print quota system is now DENY instead of ALLOW,
1822          since ALLOW can generate inaccurate results
1823          (incorrect job sizes charged to the wrong persons)
1824         
1825        - LPRng support works !
1826       
1827        - A bug was introduced some time ago wrt printers' default
1828          policy for unknown users. It is now corrected.
1829       
1830        - repykota now displays prices per job and per page for each
1831          printer, if they are defined.
1832         
1833        - Minor display bug fixed in repykota.
1834       
1835        - Problem when running repykota with an empty database was fixed.
1836       
1837    - 1.03 :
1838   
1839        - Upgrade script included for earlier versions.
1840          Please look inside the initscripts subdirectory.
1841          THE DATABASE SCHEMA HAS CHANGED, PLEASE UPGRADE.
1842         
1843        - repykota now reports account balances too.
1844       
1845        - PyKota now has a nice logo, see the logos
1846          subdirectory.
1847       
1848        - Manual pages were finally updated.
1849       
1850        - Group quotas seem to work now !
1851       
1852        - The new database schema allows to keep an history of all
1853          jobs as well as charge users per page and/or per job,
1854          and track users' account balance.
1855         
1856        - edpykota now accepts much more command line options to 
1857          use the new functionnalities. See edpykota --help for
1858          details.
1859         
1860        - The installation script now allows to install the sample
1861          configuration file during first installation.
1862         
1863        - More group quota code works, but still not finished. 
1864       
1865        - The CGI script displays a link to PyKota's website.
1866       
1867        - The job history is now kept, this will allow per-period
1868          reports in the future.
1869         
1870        - After having modified the quota for an user with edpykota,
1871          a quota check is done to eventually warn the user/admin about
1872          a quota which is too low to print.
1873         
1874        - A workaround is provided for HP Printers : their internal
1875          page counter is only saved to NVRAM in a 10 increment, so
1876          if you switch them off and then on, the reported page counter
1877          may be lower than the real number of pages printed.
1878          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
1879          We unconditionnally set the last job's page count to
1880          abs(int((10 - abs(lastcounter(snmp) - lastcounter(storage)) / 2))
1881          in this case.
1882          For a more accurate accounting, never switch your HP printers
1883          off.
1884         
1885        - A fix is provided for printers which only have a volatile 
1886          page counter (reset to 0 every time you switch the printer on)
1887          This should allow PyKota to work reasonably fine with HP Laserjet
1888          4L/5L/6L, not perfect, but better than nothing.
1889          See http://web.mit.edu/source/third/lprng/doc/LPRng-HOWTO-15.html
1890          For a more accurate accounting, never switch your HP printers
1891          off. This is untested, please report any problem.
1892         
1893        - A bug was fixed when edpykota --add was used with users who already
1894          had a quota on the specified printer.
1895         
1896        - A small display bug in repykota was introduced in preliminary
1897          1.03 versions, and fixed later on.
1898         
1899        - Some minor bugs which happened in rare situations were fixed.
1900       
1901        - Support for AppleTalk printers was added, see sample configuration
1902          file for details.
1903         
1904        - Users and group printing can now be controlled (limited) either by 
1905          print quota or by account balance.
1906       
1907    - 1.02 :
1908   
1909        - The installation script now checks for software availability
1910          and in case a software is missing asks the user if he
1911          wants to continue with the installation or abort it.
1912         
1913        - The configuration file pykota.conf is now expected to be
1914          found in /etc instead of in /etc/cups
1915          The installation script prompts the user to see if he
1916          wants to move an old configuration file to the new location
1917          if needed.
1918         
1919        - Improved documentation.
1920       
1921        - You can now set the tcp/ip port on which the Quota Storage
1922          Server is listening, see sample configuration file for details.
1923       
1924        - Better general error handling.
1925       
1926        - Upgrade script for pre 1.01 PostgreSQL database schema is now
1927          included as well.
1928       
1929    - 1.01 :
1930   
1931        - The configuration file now accepts an option   
1932          to choose the recipient(s) of the email messages :
1933         
1934            - DevNull means no one will receive them.
1935            - User means only the user will receive them.
1936            - Admin means only the admin will receive them.
1937            - Both means the User and the Admin will receive them.
1938           
1939        - The configuration file now uses hard-coded default values
1940          when an option is not set. See sample configuration file
1941          for details.
1942         
1943        - Manual pages are included since 1.00, but I forgot to   
1944          add this information to this file.
1945         
1946        - Redistribution terms for the official package have
