There are a lot of look and feels (LaF later) for programs written in java.

jgoodies, napkin and substance. If you run a command file
with the bat extension (on Windows) or with the sh extension (for
other Operation Systems), you will see the Checkersland program
with a new interface style.
After every start the
program searchs in the
languages directory for files with new
languages and loads them. Name of files should be like
i18n_XX.properties (here XX is a
two chars language code).
A file content should be in utf-8 encoding. All successfully downloaded
languages will be added into the language list of the settings window.

skins directory. Every skin should be in a
separated directory and consist of a set of images and
the skin.ini file with additional settings.
a skin example with detail information. After loading all loaded

PDN (Portable Draughts Notation) is the most popular format for storing games in text files. It allows to keep a lot of games in a single file. Moreover every game may contain many additional information: players' names, the name of tournament, the place and date of the game etc. The details of this format are available here: http://en.wikipedia.org/wiki/Portable_Draughts_Notation.
The Checkersland program allows to watch a loaded PDN file as a list of games and edit it. Some games in the games list can be highlighted: red - game data is incomplete (e.g. kind of checkers is absent) or game history is invalid, blue - game data was changed and therefore will be modified while saving.
There is special view mode of round-robin tournaments. The program
can restore crosstable of tournament and paints it in
initial state. An example with such tournaments
is available in the
The program allows to load any game from the list or from the
crosstable, watch it, edit and store changings.
There are many programs that support PDN format. Also there are huge number of PDN files for different kind of checkers. Usually, such files don't contain information about destination kind of checkers. In this case all games will be highlighted by red color after file loading. To avoid this you should set a default kind of checkers for PDN files (Options > Settings > PDN files > Game type). This setting doesn't affect storing of PND files, and kind of checkers is always stored.
