Java: triple curl support

I received some comment codes, unlike any code I've encountered before:

//{{{ Imports
import imports;
//}}}

Each method block is the same,

//{{{ above the code block  
//}}} below the code block

Solution

A quick search for "three curls" indicates that it is "Emacs folding mode"

Or any other code folding tag
