Comments that occupy several lines by themselves; so called because in assembler and C code they are often surrounded by a box in a style similar to this:

 /*************************************************
 *

* This is a boxed comment in C style *

*************************************************/

Common variants of this style omit the asterisks in column 2 or add a matching row of asterisks closing the right side of the box. The sparest variant omits all but the comment delimiters themselves; the "box" is implied.

Opposite of winged comments.
