INSTRUCTIONS:
****************************************************
You will now be prompted for all needed translations.
Please translate the requested lines, hitting [enter]
goes to the next one. You may stop at any time using
ctrl+c, and pick up where you left off by running
translation_tool again.

If there are escapes in the original English, you may
need to include them in your translation. The
following is a list of escapes and what they do:
%h - HTML code inserted at run-time
%s - Nontranslated string inserted at run-time (such as username)
\\" - A double quote (")

When you have finished your translation, make a tarball
of the lang/ directory and send it to Simo (simo@neotuli.net)
for inclusion in the AUR.
By submitting a translation, you are implying that you
are also willing to maintain it. When there are
new strings to be translated, you will be contacted.
