writing systemd unit file and specfile for a python twistd application

I have given a task to write the systemd unit file for a python twistd application and create rpm of it. The application is open source and you can find it here: http://ift.tt/1ErLIgq.

I have written the unit file as:

[Unit]
Description=ECManaged Agent for monitoring and deployment

[Service]
Type=simple
PIDFile=/opt/ecmanaged/ecagent/twistd.pid
#ExecStart=/usr/bin/twistd -y /opt/ecmanaged/ecagent/ecagentd.tac
ExecStart=\
        /bin/twistd \
        --nodaemon \
        --pidfile=/opt/ecmanaged/ecagent/twistd.pid \
        --no_save \
        --python=/opt/ecmanaged/ecagent/ecagentd.tac

WorkingDirectory=/opt/ecmanaged/ecagent
Restart=always
RestartSec=5min

[Install]
WantedBy=multi-user.target

And the specfile:

%define name      ecmanaged-ecagent
%define ename     ecagentd
%define pname     ecmanaged

I know its a bit weird that the application does not use setuptools.

Am I doing it well? How can I make it better? any pointer and suggestion will be highly appreciated.
