=head1 NAME
Regexp::Common::whitespace -- provides a regex for leading or
trailing whitescape
=head1 SYNOPSIS
use Regexp::Common qw /whitespace/;
while (<>) {
s/$RE{ws}{crop}//g; # Delete surrounding whitespace
}
=head1 DESCRIPTION
Please consult the manual of L<Regexp::Common> for a general description
of the works of this interface.
Do not use this module directly, but load it via I<Regexp::Common>.
=head2 C<$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 C<-keep>.
