" Virata AConfig Configuration Script syntax
"  Can be detected by: 1) Extension .hw, .sw, .pkg and .module
"		       2) The file name pattern "mk.*\.cfg"
"		       3) The string "Virata" in the first 5 lines


" Setup Syntax:
" quit when a syntax file was already loaded
if exists("b:current_syntax")
  finish
endif
"  Virata syntax is case insensitive (mostly)
syn case ignore
