Three curly brackets, {{{ What purpose do they serve ? }}}

[christophermann]

I've been reviewing code, and from time to time (like in PEAR's Log class, or PHPDoc's Dia2code converter) I've come across the following

// {{{ class foo
class foo
{
// {{{ function foo
function foo ()
{
} // }}}
} // }}}

Why is that ?

Is it just readability or does emacs or some application do something with they weird comments ?

Probably the last - unless someone thinks that it makes it easier to search for function and class definitions (which is debatable).
