      3 This is the Intel ACPI Component Architecture, Intel's reference
      4 implementation of the core operating system ACPI support.  The
      5 portion in the acpica/ subdirectory is provided by the operating
      6 system as the glue between the OS and the ACPICA.
      7 
      8 Please, do not import an updated ACPICA snapshot from Intel unless
      9 you absolutely know what you're doing -- The Intel directory layout
     10 changes from release to release, and we must munge it (by hand) into
     11 something sane that we can use. The current version of munge is:
     12 
     13 	mv source/* .
     14 	rmdir source
     15 	mv components/* .
     16 	rmdir components
     17 
     18 This is done using the acpica2netbsd script
     19 Please also update ACPI_DATE in include/acapps.h.
     20 
     21 The routines that the operating system must provide are documented
     22 in the following document:
