There are many different CrOS devices so the build +# system provides configuration variables that permit a CrOS build to +# control the cross-compilation tool chain. However, requiring such +# fine-grain specification is tedious for build-bots and developers. +# Consequently, the CrOS build system defaults to a convenience +# compilation mode where the compilation host is also the build target. +# +# Chrome can be compiled in this way with the gn variable: +# +# target_os = "chromeos" +# +# To perform a board-specific build, first obtain the correct system +# root (http://goo.gl/aFB4XH) for the board. Then configure GN to use it +# by setting appropriate cross-compilation variables. +# +# For example, to compile a Chrome source tree in /g/src for an +# auron_paine CrOS device with the system root cached in /g/.cros_cache, +# the following GN arguments must be provided to configure +# cross-compilation with Goma acceleration.
