=head1 NAME
URI::Find::Schemeless - Find schemeless URIs in arbitrary text.
=head1 SYNOPSIS
require URI::Find::Schemeless;
my $finder = URI::Find::Schemeless->new(\&callback);
The rest is the same as URI::Find.
=head1 DESCRIPTION
URI::Find finds absolute URIs in plain text with some weak heuristics
for finding schemeless URIs. This subclass is for finding things
which might be URIs in free text. Things like "www.foo.com" and
"lifes.a.bitch.if.you.aint.got.net".
The heuristics are such that it hopefully finds a minimum of false
positives, but there's no easy way for it know if "COMMAND.COM" refers
to a web site or a file.

# Originally I constrained what couldn't be before the match
# like this: don't match email addresses, and don't start
# anywhere but at the beginning of a host name
# (?<![\@.$dnsSet])
# but I switched to saying what can be there after seeing a
# false match of "Lite.pm" via "MIME/Lite.pm".
(?: ^ | (?<=[\s<>()\{\}\[\]]) )
# hostname
(?: [$dnsSet]+(?:\.[$dnsSet]+)*\.$tldRe
| (?:\d{1,3}\.){3}\d{1,3} ) # not inet_aton() complete
(?:
(?=[\s\Q$cruftSet\E]) # followed by unrelated thing
(?!\.\w) # but don't stop mid foo.xx.bar
(?<!\.p[ml]) # but exclude Foo.pm and Foo.pl
|$ # or end of line
(?<!\.p[ml]) # but exclude Foo.pm and Foo.pl
|/[$uricSet#]* # or slash and URI chars
)
}x;
}
=head3 top_level_domain_re
my $tld_re = $self->top_level_domain_re;
Returns the regex for matching top level DNS domains. The regex shouldn't
be anchored, it shouldn't do any capturing matches, and it should make
itself ignore case.
