=============================================================================

pkpgcounter News :

  * 3.51 :

    - Partial rewrite of the PostScript parser, with huge performance increase.

    - Fixed a problem in the PostScript parser where the number of copies set with
      e.g. "dvips -c 9 -o output.ps input.dvi" wasn't correctly detected.

    - Increased accuracy in the PDF parser, with some speed expense but
      some big room for future improvements.

    - Added support for Structured Fax documents in page counting mode.

    - Added support for ASCII PNM (Netpbm) documents in page counting mode.

    - Fixed a problem with the parsing of SPL1 (GDI) documents : all such
      documents should now be correctly parsed.

    - Improved the PCL3/4/5 parser.

  * 3.40 :

    - Fixed a major bug in the detection of OpenDocument (ISO/IEC DIS 26300)
      files.

    - Added support for page counting in Microsoft Word (c) (tm) (r) (etc...)
      documents.

    - Added support for ink accounting in Microsoft Word (c) (tm) (r) (etc...)
      and OpenDocument (ISO/IEC DIS 26300) documents.

  * 3.30 :

    - Added support for all file formats supported by the Python Imaging
      Library.

      produced by the hpijs driver.

    - Major code cleaning.

  * 3.20 :

    - Added a minimal parser for Brother HBP documents.

    - Added support for Canon ImageRunner commands to the PCLXL parser,
      much like it was already done for the PCL3/4/5 parser.

  * 3.10 :

    - Fixed another problem in the code handling the output of Canon's
      ImageRunner printer drivers.

  * 3.00 :

    - Fixed a problem in the code handling the output of Canon's ImageRunner

    - Fixed an incompatibility with Python v2.5

  * 2.17 :

    - Fixed problems in the handling of PJL number of copies (COPIES= and QTY=)
      which caused the number of copies for each page to be squared.

  * 2.16 :

    - Fixed a problem in the PCL3/4/5 parser to accomodate line based
      report generators which expect the printer to skip to next page
      based on lines per page instead of sending a specific command.

  * 2.15 :

    - Fixed a regexp in the PDF parser which caused some files to be
      incorrectly accounted for.

      comments.

  * 2.13 :

    - Nowrecognizes the GC colorspace if you only want to differentiate
      grayscale pages from coloured pages. In this colorspace, the
      percents are always "G : 100.0   C : 0.0" or "G : 0.0   C : 100.0"
      respectively for a grayscale page and a coloured page.

  * 2.12 :

    - Fixed a problem with the PostScript parser.

  * 2.11 :

    - Improved overall robustness in ink accounting mode.

  * 2.10 :

    - Added a plain text parser, with support for both page counting and
      ink coverage.

    - Added a minimal SPL1 parser.

    - Fixed a problem in the PCLXL parser related to Kyocera printer drivers.

      table driven.

    - Improved the PostScript parser.

  * 1.85 :

    - Added support for Samsung QPDL (aka SPL2) file format in page
      counting mode, thanks to the work done by Aur�en Croc on
      reverse engineering the file format.

  * 1.85alpha :

    - Added test document and program to generate the test document
      to check the functionning of the ink coverage computation algorithm.

  * 1.84 :

    - Computation of ink coverage now works and is documented.
      The supported file formats are : PS, PDF, PCLXL, PCL3/4/5,
      DVI and TIFF.

  * 1.84alpha :

    - Added initial support for the computation of ink coverage.
