Dear Monks,

I am learning perl. When I use a Regexp::Assemble module i have a little bit doubt.

I Created Regexp for the following:

use Regexp::Assemble;
my $ra=Regexp::Assemble->new;
$ra->add('Text.');
$ra->add('TEXT.');
$ra->add('Texts');
print $ra->re;

[download]

I got the output 

(?-xism:T(?:EXT.|ext.))

[download]

Please teach me what is mean by ?-xism:

Thank You
