:boxed comments: n. Comments (explanatory notes attached to program
instructions) that occupy several lines by themselves; so called
because in assembler and C code they are often surrounded by a box
in a style something like 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. Oppose {winged comments}.
