+ * This library exists to understand and parse the pci.ids database that is
+ * maintained at http://pci-ids.ucw.cz/ and in the gate at cmd/hwdata. This
+ * database provides a way to map the PCI device, vendor, and subsystem ids to
+ * a human understandable name.
+ *
+ * This library exports this data in a similar way to a tree. The handle that
+ * is returned from pcidb_open is the root of the tree. The next level are the
+ * vendors. Each vendor has a unique set of devices and each device has a unique
+ * set of subvendor and subdevice pairs.
+ *
+ * Parsing information:
+ *
+ * The database is formatted in the following basic format:
+ * vendor_id<two spaces>vendor_name
+ * <tab>device_id<two spaces>device_name
+ * <tab><tab>subvendor<space>subdevice<two spaces>subsystem_name
+ *
+ * For any given vendor, there can be multiple devices. And for any given device
