       darktable is a digital photography workflow application for Linux and Mac OS X in the
       lines of Adobe Lightroom and Apple Aperture.

       The application is designed to ease editing and consistent processing of large photo
       sessions and provides a easy to use digital light-table and a set of sophisticated post-
       processing tools.

       Most processing is done in 32-bit floating point per channel mode in device independent
       CIE L*a*b* color space. darktable is also fully color managed, which gives you full
       control over the look of the photos.

       The application relies on a modern plug-in architecture thus making it easy for 3rd party
       developers to extend the existing capabilities of the application.  All light-table and
       darkroom features are implemented as plug-ins, so you can create your plug-ins reusing
       existing code.


       IMG_1234.RAW or image_folder/
           You may optionally supply the filename of an image or the name of a folder containing
           image files. If a filename is given darktable starts in darkroom view with that file
           opened. If a folder is given darktable starts in lighttable view with the content of
           that folder as the current collection.

       -d <debugoption>
           This option enables debug output to the terminal. There are several subsystems of
           darktable and debugging of each of them can be activated separately. You can use this
           option multiple times if you want debugging output of more than one subsystem.

           A few of those debugoptions are:

               Enable job queue debugging. If you redirect darktable's output to control.log and
               call ./tools/ control.log, you will get a nice control.svg
               with a visualization of the threads' work.

               This will give you a lot of debugging info about the mipmap cache for light table
               mode. If compiled in debug mode, this will also tell you where in the code a
               certain buffer has last been locked.

               Use this for performance tweaking your darkroom modules. It will rdtsc-measure the
               runtimes of all plugins and print them to stdout.

           all Enable all debugging output.

           Prevent darktable from initializing the OpenCL subsystem. Use this option in case
           darktable crashes at startup due to a defective OpenCL implementation.

       --library <library file>
           darktable keeps image information in an sqlite database for fast access. The default
           location of that database file is "$HOME/.config/darktable/library.db". You may give
           an alternative location, e.g. if you want to do some experiments without compromising
           your original library.db. If the database file does not exist, darktable creates it
           for you. You may also give ":memory:" as a library file in which case the database is
           kept in system memory - all changes are discarded when darktable terminates.

       --datadir <data directory>
           This option defines the directory where darktable finds its runtime data. The default
           place depends on your installation. Typical places are
           "/opt/darktable/share/darktable/" and "/usr/share/darktable/".

       --moduledir <module directory>
           darktable has a modular structure and organizes its modules as shared libraries for
           loading at runtime. With this option you tell darktable where to look for its shared
           libraries. The default place depends on your installation; typical places are
           "/opt/darktable/lib64/darktable/" and "/usr/lib64/darktable/".

       --tmpdir <tmp directory>
           The place where darktable stores its temporary files. If this option is not supplied
           darktable uses the system default.

       --configdir <config directory>
           This option defines the directory where darktable stores the user specific
           configuration. The default place is "$HOME/.config/darktable/".

       --cachedir <cache directory>
           darktable keeps a cache of image thumbnails for fast image preview and of precompiled
           OpenCL binaries for fast startup. By default the cache is located in
           "$HOME/.cache/darktable/". There may exist multiple thumbnail caches in parallel - one
           for each library file.

       --localedir <locale directory>
           The place where darktable finds its language specific text strings.  The default place
           depends on your installation. Typical places are "/opt/darktable/share/locale/" and

       --conf <key>=<value>
           darktable supports a rich set of configuration parameters which the user defines in
           "darktablerc" - darktable's configuration file in the user config directory. You may
           temporarily overwrite individual settings on the command line with this option -
           however, these settings will not be stored in "darktablerc".

       The project was started by Johannes Hanika in early 2009 to fill the gap (or, rather, a
       black hole) of a digital photography workflow tool on Linux.
