1# This script generates the PS3 hypervisor call header from a hypervisor
2# interface definition file. All lines that do not begin with HVCALL
3# or a bare # for comments are copied to the output header so that
4# enums, constant, C comments and the like can be passed through into the
5# header.

7# Invoke like so: awk -f ps3-hv-header.awk < ps3-hvcall.master > ps3-hv.h
