+dnl This configure script is complicated, because GRUB needs to deal
+dnl with three potentially different types:
+dnl
+dnl   build  -- the environment for building GRUB
+dnl   host   -- the environment for running utilities
+dnl   target -- the environment for running GRUB
+dnl
+dnl In addition, GRUB needs to deal with a platform specification
+dnl which specifies the system running GRUB, such as firmware.
+dnl This is necessary because the target type in autoconf does not
+dnl describe such a system very well.
+dnl
+dnl The current strategy is to build utilities using host
+dnl cross-compiler and grub core and modules using target
+dnl cross-compiler.  For this we use nested packages approach, where
+dnl top-level package grub utilities is built with HOSTCC and nested
+dnl package (in grub-core directory) builds with TARGETCC.
