 At the bottom level, the interface consists of Web RPCs.

+BOINC provides client-side bindings in PHP, C++, and Python.
 These bindings differ slightly; they expose different details of the Web RPCs.
 
-As jobs are completed, their output files are available to the submitting user via HTTP.
-When a batch is complete, a zipped archive of all its output files is available via HTTP.
-Details are [RemoteOutputFiles here].
+Interfaces for [RemoteInputFiles staging input files]
+and [RemoteOutputFiles fetching output files] are described separately.

+There are various options for managing input files.
+If you use the [RemoteInputFiles#Job-basedfilemanagement Job-based file management],
+which maintains batch/file associations,
+the order of operations is:
+
+ * Create a batch (initially empty); returns the batch ID.
+ * Stage input files, passing the batch ID
+ * Submit jobs, passing the batch ID
+
+If you manage input files a different way,
+then you create the batch and submit jobs in a single API call.
