# File:        d3dxerr.w
# Purpose:     Generates d3dxerr.h and d3dxerrswitch.h
# Includes:    d3dxerrdef.w
#
# Description: d3dxerr.h is an external D3DX header containing D3DXERR_*
#              definitions. d3dxerrswitch.h contains the guts of a C switch
#              statement that assigns strings to an LPSTR based on a given 
#              D3DXERR_.  The switch statement which #includes d3dxerrswitch.h
#              is in the implementation of D3DXGetErrorString in d3dx.cpp.
#
# Usage:       m4 d3dxerr.w > d3dxerr.h
#              m4 -Dswitch d3dxerr.w > d3dxerrswitch.h
