The files server/gnun/generic.lang.html are special: if
no such file exists for your language, an empty file will be created
(and added to the repository if specified
VCS=yes). This file
is optional, and should contain a short message in your native
language, ideally providing more information about the translation
team or where to report bugs. For example:
<p>To join the Fooish translation team, see <a href="http://gnu.org/server/standards/translations/foo">the Foo team homepage</a>.</p>
The contents of generic.lang.html is injected right after the translators’ credits, if any, and before the timestamp. It should be valid HTML markup.
When you modify this file, for example, adding a message to the existing empty file or changing a URL, such modification will affect all articles of the language lang in generic.lang.html. The next time a build occurs, all translations of the language code lang (i.e. all .lang.html, including the homepage), will be modified to include the contents of this special file.
