+ *
+ * \brief The Acquire system is responsible for retrieving files from
+ * local or remote URIs and postprocessing them (for instance,
+ * verifying their authenticity). The core class in this system is
+ * pkgAcquire, which is responsible for managing the download queues
+ * during the download. There is at least one download queue for
+ * each supported protocol; protocols such as http may provide one
+ * queue per host.
+ *
+ * Each file to download is represented by a subclass of
+ * pkgAcquire::Item. The files add themselves to the download
+ * queue(s) by providing their URI information to
+ * pkgAcquire::Item::QueueURI, which calls pkgAcquire::Enqueue.
+ *
+ * Once the system is set up, the Run method will spawn subprocesses
+ * to handle the enqueued URIs; the scheduler will then take items
+ * from the queues and feed them into the handlers until the queues
+ * are empty.
+ *
+ * \todo Acquire supports inserting an object into several queues at
+ * once, but it is not clear what its behavior in this case is, and
+ * no subclass of pkgAcquire::Item seems to actually use this
+ * capability.
