### Tab blocks

There are special blocks surrounded by four slashes («////»). They mark text, which will be rendered as part of a tab in the final document. The scheme is:

    //// tab | {tab title}
    {tab content, may span many lines}
    ////

Keep everything before the vertical bar («|») as is, including the vertical bar. Translate the tab title. Translate the tab content, applying the rules you know. Keep the four block closing slashes as is.
