<p>This can be the most interesting part, requiring choices for</p>
<ul class="simple">
<li>suite durability</li>
<li>common libraries coding</li>
<li>ensuring maintainability</li>
</ul>
<p>The CDP client provides an environment where CDP variables, aliases and
functions are global entities. Choosing ksh to design a suite will
lead to similar concepts and practices. Choosing the Python language can
lead to deeper changes.</p>
<p>Milestones are:</p>
<ul class="simple">
<li>the expanded definition file generation</li>
<li>the expanded definition file load into ecFlow server</li>
<li>running the (e)suite</li>
<li>eventually, expanded definition files played into SMS server, and run
as (e)suite</li>
</ul>
