=head1 NAME
Regexp::Common::URI -- provide patterns for URIs.
=head1 SYNOPSIS
use Regexp::Common qw /URI/;
while (<>) {
/$RE{URI}{HTTP}/ and print "Contains an HTTP URI.\n";
}
=head1 DESCRIPTION
Patterns for the following URIs are supported: fax, file, FTP, gopher,
HTTP, news, NTTP, pop, prospero, tel, telnet, tv and WAIS.
Each is documented in the I<Regexp::Common::URI::B<scheme>>,
manual page, for the appropriate scheme (in lowercase), except for
I<NNTP> URIs which are found in I<Regexp::Common::URI::news>.
=head2 C<$RE{URI}>
Return a pattern that recognizes any of the supported URIs. With
C<{-keep}>, only the entire URI is returned (in C<$1>).
