This is a port of library lcms2 2.15 to MSDOS/DJGPP.


  The little cms library intends to be a small-footprint, speed optimized color
  management engine in open source form written in C.
  Here some features taken from the information provided by the lcms home page
  http://www.littlecms.com:
    Basic features:
      Widely portable.
      Easy to use.
      Small, tight code.
      Fast, optimized for speed.
      Handles a wide range pixel formats.
      Implements ICC spec 4.2
      Profile to profile and multiprofile transforms.
      Supports all kind of profiles, including named color
      PostScript CSA and CRD generation

    Advanced features:
      Full multicolor support, including proof direction in more than 4 inks.
      Black preservation on CMYK->CMYK transforms.
      Gamut checking.
      Softproofing.
      Precalculated device link transforms with prelinearization step.
      Virtual Gray, RGB profiles.
      CIECAM02 appearance model.
      Can write profiles as well.
      Built-In profiles.
      Specialized abstract virtual profiles.
      Ink limiting.

  Please note that this is a library only for programmers.  If you do not
  understand all these, you do not need the port.  lcms is a CMM engine;
  it implements fast transforms between ICC (international color consortium)
  profiles.  lcms is NOT a file format or display library.  lcms knows nothing
  about how to display bitmaps (JPEG, TIFF, GIF or whatever).



  DJGPP specific changes.
  =======================


  The port has been adjusted and fixed to be compiled with DJGPP 2.0X (CVS
  repository code).  Please note that the sources may not be compilable if
  LFN support is not available.

  All DJGPP specific stuff is stored in the "djgpp" directory.

  To configure and compile the package you will have to install the following
  packages:
    http://ftp.delorie.com/pub/djgpp/current/v2tk/zlb1213b.zip
    http://ftp.delorie.com/pub/djgpp/current/v2tk/xz-525a.zip
    http://ftp.delorie.com/pub/djgpp/current/v2tk/tiff450b.zip
    http://ftp.delorie.com/pub/djgpp/current/v2tk/png1639b.zip
    http://ftp.delorie.com/pub/djgpp/current/v2tk/jpeg9eb.zip
    http://ftp.delorie.com/pub/djgpp/current/v2tk/jbig21br2.zip
  Of course, you can always download newer versions of these ports if available.

  To configure and compile this port at least the following version of
  Bash, Make and pkg-config are required:
    http://ftp.delorie.com/pub/djgpp/current/v2gnu/bsh4428b.zip
    http://ftp.delorie.com/pub/djgpp/current/v2gnu/mak44b.zip
    http://ftp.delorie.com/pub/djgpp/current/v2tk/pkc025b.zip
  No previous versions will work nor are supported.  Any future version should
  work.

  For the people interested in the output of the build process, the following
  output files have been stored in the "djgpp" directory of the binary archive:
    _co_log.txt: console output of the configuration step.
    _mo_log.txt: console output of the compilation step.
    _mc_log.txt: console output of the check step.
    _mi_log.txt: console output of the installation step.

  The source package has been configured to be build in the "0build" directory
  located under the top source directory.  If for some reason you need to
  reconfigure the sources delete the complete contain of the "0build" directory
  and run the following command:
    ..\djgpp\config.bat ./..



  Here is an extract of the ChangeLog file showing the user visible changes
  from the last port (library lcms2 2.14) to this one:

-------------------------------------------------------------------------------

-----------------------
2.15 Maintenance release
-----------------------
New MESON build system, many thanks to amispark and Lovell Fuller for bringing this.
Fixed a bug that caused memory corruption on colord
cmsReadRawTag can read portions  of tags again. Removing this caused colord to segfault when dumping profiles
Added more checks based of fuzzer discoveries.
MSYS2 can now compile lcms2
Checked on Apple Silicon M1 and M2
Fixed a bug of fastfloat plug-in that affected Krita CMYK color selector


-------------------------------------------------------------------------------




  The port consists of the usual three packages that have been produced using
  djdev20X (CVS repository code) and can be downloaded from ftp.delorie.com
  and mirrors as (time stamp 2023-05-13):
