 == Determining Output: <code>HISTORY.rc</code> ==
+The contents of the the file <code>HISTORY.rc</code> (in your experiment <code>HOME</code> directory) tell the model what and how to output its state and diagnostic fields.  The default <code>HISTORY.rc</code> provides many fields as is, but you may want to modify it to suit your needs.
+===File format===
+The top of a default <code>HISTORY.rc</code> will look something like this:
+<pre>
+EXPID:  myexp42
+EXPDSC: this_is_my_experiment
+COLLECTIONS: 'geosgcm_prog'
+             'geosgcm_surf'
+             'geosgcm_moist'
+             'geosgcm_turb'
+</pre>
+[....]
+The field <code>EXPID</code> must match the name of the experiment <code>HOME</code> directory; this is only an issue if you copy the  <code>HISTORY.rc</code> from a different experiment.  The <code>EXPDSC</code> field is used to label the plots.  The <code>COLLECTIONS</code> field contains list of strings indicating the output collections to be created.  The content of the individual collections are determined after this field.  Individual collections can be "turned off" by commenting the relevant line with a <code>#</code>.
