   4 # It sets various shell variables based on the the target and the
   5 # configuration options.  You can modify this shell script without
   6 # needing to rerun autoconf.

   8 # This shell script should be invoked as
   9 #   . configure.target
  10 # If it encounters an error, it will exit with a message.

  12 # It uses the following shell variables:
  13 #   target                The configuration target
  14 #   target_cpu            The configuration target CPU
  15 #   target_os             The configuration target OS
  16
  17 # It possibly modifies the following shell variables:
  18 #   cpu_include_dir        CPU-specific include directory, relative to srcdir
  19 #   os_include_dir         OS-specific include directory, relative to srcdir
  20
