 pkgdesc="Bitmessage is a P2P communications protocol used to send encrypted messages to another person or to many subscribers. It is decentralized and trustless, meaning that you need-not inherently trust any entities like root certificate authorities. It uses strong authentication which means that the sender of a message cannot be spoofed, and it aims to hide "non-content" data, like the sender and receiver of messages, from passive eavesdroppers like those running warrantless wiretapping programs."

         <source>When someone sends you a message, their computer must first complete some work. The difficulty of this work, by default, is 1. You may raise this default for new addresses you create by changing the values here. Any new addresses you create will require senders to meet the higher difficulty. There is one exception: if you add a friend or acquaintance to your address book, Bitmessage will automatically notify them when you next send a message that they need only complete the minimum amount of work: difficulty 1. </source>
         <translation>Когда кто-либо отправляет Вам сообщение, его компьютер должен сперва решить определенную вычислительную задачу. Сложность этой задачи по умолчанию равна 1. Вы можете повысить эту сложность для новых адресов, которые Вы создадите, здесь. Таким образом, любые новые адреса, которые Вы создадите, могут требовать от отправителей сложность большую чем 1. Однако, есть одно исключение: если Вы специально добавите Вашего собеседника в адресную книгу, то Bitmessage автоматически уведомит его о том, что для него минимальная сложность будет составлять всегда всего лишь 1.</translation>

         <source>&lt;html&gt;&lt;head/&gt;&lt;body&gt;&lt;p&gt;Bitmessage can utilize a different Bitcoin-based program called Namecoin to make addresses human-friendly. For example, instead of having to tell your friend your long Bitmessage address, you can simply tell him to send a message to &lt;span style=&quot; font-style:italic;&quot;&gt;test. &lt;/span&gt;&lt;/p&gt;&lt;p&gt;(Getting your own Bitmessage address into Namecoin is still rather difficult).&lt;/p&gt;&lt;p&gt;Bitmessage can use either namecoind directly or a running nmcontrol instance.&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</source>

+        <translation>&lt;html&gt;&lt;head/&gt;&lt;body&gt;&lt;p&gt;Bitmessage умеет пользоваться программой Namecoin для того, чтобы сделать адреса более дружественными для пользователей. Например, вместо того, чтобы диктовать Вашему другу длинный и нудный адрес Bitmessage, Вы можете попросить его отправить сообщение на адрес вида &lt;span style=&quot; font-style:italic;&quot;&gt;test. &lt;/span&gt;&lt;/p&gt;&lt;p&gt;(Перенести Ваш Bitmessage адрес в Namecoin по-прежнему пока довольно сложно).&lt;/p&gt;&lt;p&gt;Bitmessage может использовать либо прямо namecoind, либо уже запущенную программу nmcontrol.&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</translation>
