=head1 NAME

rt-crontool - a tool to act on tickets from an external scheduling tool

=head1 SYNOPSIS

    # find all active tickets in the queue 'general' and set their priority to 99 if they are overdue:
    rt-crontool \
      --search RT::Search::ActiveTicketsInQueue  --search-arg general \
      --condition RT::Condition::Overdue \
      --action RT::Action::SetPriority --action-arg 99 \
      --verbose

    # Escalate tickets
      rt-crontool \
        --search RT::Search::ActiveTicketsInQueue  --search-arg general \
        --action RT::Action::EscalatePriority

=head1 DESCRIPTION

This script is a tool to act on tickets from an external scheduling tool, such
as cron.

Security:

This tool allows the user to run arbitrary perl modules from within RT. If
this tool were setgid, a hostile local user could use this tool to gain
administrative access to RT. It is incredibly important that nonprivileged
users not be allowed to run this tool. It is suggested that you create a
non-privileged unix user with the correct group membership and RT access to
run this tool.
