=head1 NAME

sanitycheck.pl - Perl script to perform a sanity check at the command line

=head1 SYNOPSIS

 ./sanitycheck.pl [--verbose] --login <user@domain.com>

=head1 OPTIONS

=over

=item B<--help>

Displays this help text

the script will return only errors. With the option, the script will append
all output to the email.

This should be passed the email address of a user that is capable of
running the Sanity Check process, a user with the editcomponents priv. This
user will receive an email with the results of the script run.

=head1 DESCRIPTION

This script provides a way of running a 'Sanity Check' on the database
via either a CLI or cron. It is equivalent to calling sanitycheck.cgi
via a web broswer.
