PyKota Print Quota System

Several new configuration directives were
introduced to increase the software's versatility.
You can now control the ordering in the output of
the data dumper, either from the command line or
when it's used as a CGI script. The "grey vs
color" pseudo colorspace is now supported in ink
accounting mode. Several minor improvements and
bugfixes were done all over the place.

The most important new feature is support for the
accounting of ink usage. Several improvements were
done all over the place in both usability and
configurability. A lot of bugs were fixed.

Many fixes were made to accommodate MySQL
"features". A locking mechanism has been
introduced to allow several print servers to
access the same device without mixing print jobs
and banners. More environment variables are now
accessible to the print administrators' own
scripts. The pkipplib library is now used to
directly interact with the print server.

MySQL and SQLite are now fully supported. A major
rewrite of the command line tools was done to
greately increase performance when managing
several users, groups, printers, or billing codes
at the same time. A PDF invoice generator is now
included. The print server part of a tool which
can interact with end users at printing time is
now included. Many bugfixes and documentation
improvements were done.

This release is mostly aimed at adventurous souls.
Complete MySQL support was added, but is in need
of testing. Several improvements were done to SNMP
and PJL hardware accounting routines. The whole
database can now be exported with a single
dumpykota command. The cupspykota backend may now
be stopped cleanly by print administrators. The
preaccounter directive was introduced in the
configuration file to allow people to specify
which parser should be used to pre-estimate the
number of pages in a job, in case the internal
parser is not appropriate.
