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.
