Ask Bjørn Hansen a23d4b3da9 Fix 01-syntax test failures
Exclude some tests with dependencies.

Remove -T from perl line in plugins
This makes it harder to test with PERL5LIB/perlbrew etc

=head1 NAME
auth_cvm_unix_local - SMTP AUTH LOGIN module using
Bruce Guenther's Credential Validation Module (CVM)
http://untroubled.org/cvm/
=head1 SYNOPSIS
In config/plugins:
auth/auth_cvm_unix_local \
cvm_socket /var/lib/cvm/cvm-unix-local.socket \
enable_smtp no \
enable_ssmtp yes
=head1 BUGS
- Should probably handle auth-cram-md5 as well. However, this requires
access to the plain text password. We could store a separate database
of passwords purely for SMTP AUTH, for example as an optional
SMTPAuthPassword property of an account in the esmith::AccountsDB;
=head1 DESCRIPTION
This plugin implements an authentication plugin using Bruce Guenther's
Credential Validation Module (http://untroubled.org/cvm).
