<div class="code">
 <span class="oogintro">G-2.0-plain_java-1.0</span>
 <span class="oogcomment">⊰
 
    This template demonstrates how to make your templates look good.
 
 ⊱</span>
 <span class="oogcomment">⊰
    To illustrate the first problem, note that between the first comment and
    the second one (this one) there is a line break. In templates, it is often
    desirable to have nicely layouted template code, while at the same time
    nicely layouted results. How to achieve this?
 
    First, note the three tiny continuation dots '<span class="oogcontinuation">…</span>' behind the following comment
    end delimiter:
 ⊱</span><span class="oogcontinuation">…</span>
 <span class="oogcomment">⊰
    They simple say: please ignore the line break (they are comparable to the
    use of a backslash in programming languages like C or C++).
 ⊱</span><span class="oogcontinuation">…</span>
 <span class="oogcomment">⊰
    Another problem often encountered is the indentation depth mismatch between
    template code and result code. E.g.
 ⊱</span><span class="oogcontinuation">…</span>
                               Hello, world!
 <span class="oogcomment">⊰
    is of course indented in the output by 30 spaces. How to avoid this,
    without compromising template layout? That's the purpose of the indentation
    character '⋮', like here
 ⊱</span><span class="oogcontinuation">…</span>
 <span class="oogindentation">                             ⋮</span>Hello, world!
 <span class="oogcomment">⊰
    So, if you combine these concepts, you might e.g. write
 ⊱</span><span class="oogcontinuation">…</span>
 <span class="oogindentation">                             ⋮</span>Hello, <span class="oogcontinuation">…</span>
 <span class="oogindentation">                             ⋮</span><span class="oogexpression">◂"world"▸</span><span class="oogcontinuation">…</span>
 <span class="oogindentation">                             ⋮</span>!<span class="oogcontinuation">…</span>
 <span class="oogcomment">⊰
    which creates again "Hello, world!", without any additional spaces or line
    breaks before, after of within the output.
 ⊱</span>
