About a Regular Expression Grouping Construct.

Hi, all,
Does any body know how to use this Grouping Construct?

(?> )

The following is its description in the MSDN reference:

Nonbacktracking subexpression (also known as a "greedy" subexpression). The
subexpression is fully matched once, and then does not participate piecemeal
in backtracking. (That is, the subexpression matches only strings that would
be matched by the subexpression alone.)

However, I can not understand what does it mean. If somebody knows how to
use this Grouping Construct, would you please show me an example? Thanks!

Best regards,
Laser Lu
