+ * acpidump - A portable utility for obtaining system ACPI tables and dumping
+ * them in an ASCII hex format suitable for binary extraction via acpixtract.
+ *
+ * Obtaining the system ACPI tables is an OS-specific operation.
+ *
+ * This utility can be ported to any host operating system by providing a
+ * module containing system-specific versions of these interfaces:
+ *
+ * acpi_os_get_table_by_address
+ * acpi_os_get_table_by_index
+ * acpi_os_get_table_by_name
+ *
+ * See the ACPICA Reference Guide for the exact definitions of these
+ * interfaces. Also, see these ACPICA source code modules for example
+ * implementations:
+ *
+ * source/os_specific/service_layers/oswintbl.c
+ * source/os_specific/service_layers/oslinuxtbl.c
