+ collection. If the cost data was not correctly configured at the time the
+ container was executed, the output from this program will be incorrect.
+
+ - If a container was run on a preemptible ("spot") instance, the cost data
+ reported by this program may be wildly inaccurate, because it does not have
+ access to the spot pricing in effect for the node then the container ran. The
+ UUID report file that is generated when the '-output' option is specified has
+ a column that indicates the preemptible state of the instance that ran the
+ container.
+
+ - This program does not take into account overhead costs like the time spent
+ starting and stopping compute nodes that run containers, the cost of the
+ permanent cloud nodes that provide the Arvados services, the cost of data
+ stored in Arvados, etc.
+
+ - When provided with a project uuid, subprojects will not be considered.
