It can also be downloaded from the SVN source code repository.
The root URL of the repository is http://maitreya.svn.sourceforge.net/viewvc/maitreya/. Go to the release directory (e.g. "maitreya7"). The current development is under "trunk", released versions can be found in the "tags" folder.
Open the configuration file which is located in in the configuration directory, see the Directory Layout chapter. Find the key General/langList. Add the code of your language with space separation.
Start the program and open the configuration dialog. Your language should be visible in the language list.
Make a new directory named like the code of your language in the program's folder, e.g.
Copy the file maitreya6.pot to that directory an rename it to LANG.po.
automake && autoconf && configure && make
The compiler will complain about missing header entries. Add these entries and try again.
Note: if you want to test your translation from the source code tree: create a directory
named like the language code in the gui directory. Go into that directory and link the gmo file to maitreya6.mo,
ln -s ../../po/lang.gmo maitreya6.mo.
Open the LANG.po file and translate the messages. There about 1000 messages. Compile the message catalogue to lang/maitreya6.mo (Windows) or lang.gmo (Linux/Unix) and test your translation.
You are encouraged to publish your translation for the benefit of the community.
Note: Non European languages should use a Unicode character set (UTF-8).
