+      <title>Introduction</title>
+
+      <para>The ECL Scheduler is a component process installed with the HPCC
+      system platform. It typically starts with the platform.</para>
+
+      <para>An interface to the scheduler is available through ECL Watch. The
+      ECL Scheduler interface allows you to see a list of scheduled workunits.
+      It can also trigger an event. An Event is a case-insensitive string
+      constant naming the event to trap.</para>
+
+      <para>A command line tool, <emphasis>scheduleadmin</emphasis> is
+      available on the server installed in /opt/HPCCSystems/bin.</para>
+
+      <sect2>
+        <title>ECL Scheduling</title>
+
+        <para>ECL Scheduling provides a means of automating processes within
+        ECL code or to chain processes together to work in sequence. For
+        example, you can write ECL code that watches a landing zone for the
+        arrival of a file, and when it arrives, sprays it to Thor, processes
+        it, builds an index, and then adds it to a superfile.</para>
+      </sect2>
+
+      <sect2>
+        <title>How it Works</title>
+
+        <para>ECL Scheduling is event-based. The ECL Scheduler monitors a
+        Schedule list containing registered Workunits and Events and executes
+        any Workunits associated with an Event when that Event is
+        triggered.</para>
+
+        <para>Your ECL Code can execute when an Event is triggered, or can
+        trigger an Event. If you submit code containing a <emphasis
+        role="bold">WHEN </emphasis>clause, the Event and Workunit registers
+        in the Schedule list. When that Event triggers, the Workunit compiles
+        and executes. When the Workunit completes, ECL Scheduler removes it
+        from the Schedule list.</para>
+
+        <para>For example, if you submit a Workunit using <emphasis
+        role="bold">WHEN(‘Event1’,’MyEvent’, COUNT(2)) </emphasis>in the
+        appropriate place, it will execute twice (the value of <emphasis
+        role="bold">COUNT</emphasis>) before the ECL Scheduler removes it from
+        the Schedule list and the Workunit is marked as completed.</para>
