 This component provides user-editable text fields for an Agent Panel.
+These can be used to map values into operation start arguments, or for
+other stuff.  Note checkbox and ride-along buttons are supported.
+
+Usage::
+
+   <OpParam
+     caption="Some param"
+     v-model="ops.op_name.params.param_name" />
+
+   You can apply model value filters -- e.g. use v-model.number. To
+   force blank values to return null, include::
+
+     modelValue="blank_to_null"
+
+   To make it a checkbox (which will automatically parse as a bool),
+   include::
+
+     :checkbox="true"
+
+   To include both the editable field and a clickable button, pass::
+
+     button="Button text"
+     @click-button="do_click()"
