NAME
    Regexp::Common::whitespace -- provides a regex for leading or trailing whitescape

SYNOPSIS
        use Regexp::Common qw /whitespace/;

        while (<>) {
            s/$RE{ws}{crop}//g;           # Delete surrounding whitespace
        }

DESCRIPTION
    Please consult the manual of Regexp::Common for a general description of the works of this
    interface.

    Do not use this module directly, but load it via *Regexp::Common*.

  $RE{ws}{crop}
    Returns a pattern that identifies leading or trailing whitespace.

    For example:

            $str =~ s/$RE{ws}{crop}//g;     # Delete surrounding whitespace

    The call:

            $RE{ws}{crop}->subs($str);

    is optimized (but probably still slower than doing the s///g explicitly).

    This pattern does not capture under "-keep".
