=head1 NAME
arcsign.pl - computes ARC signatures for an email message
=head1 SYNOPSIS
arcsign.pl [options] < original_email.txt
options:
--chain=pass|fail|none|ar
--domain=DOMAIN
--srvid=DOMAIN
--selector=SELECTOR
--key=FILE
--debug-canonicalization=FILE
--timestamp=INTEGER
--wrap
arcsign.pl --help
to see a full description of the various options
=head1 OPTIONS
=over
=item B<--chain>
Chain value. "ar" means pick it up from Authentication-Results header.
=item B<--key>
File containing private key, without BEGIN or END lines.
=item B<--domain>
Signing domain
=item B<--srvid>
Authentication-Results server domain, defaults to signing domain.
=item B<--debug-canonicalization>
Outputs the canonicalized message to the specified file, in addition
to computing the DKIM signature. This is helpful for debugging
canonicalization methods.
