   4 # and non-empty.
   5 #
   6 # User-settable variables:
   7 #
   8 # EMUL_TYPE.${EMUL_OPSYS}
   9 #       Specifies the "type" or "variant" of ${EMUL_OPSYS} to use, e.g.
  10 #       ${EMUL_TYPE.linux} == "suse".
  11 #
  12 # EMUL_PLATFORM
  13 #       Specifies the platform to emulate, and is of the form
  14 #       ${EMUL_OPSYS}-${EMUL_ARCH}, e.g. linux-i386.  By default
  15 #       this is the best-matching platform listed in EMUL_PLATFORMS
  16 #       chosen based on EMUL_PREFER.
  17 #
  18 # EMUL_PREFER
  19 #       The list of platforms to try to emulate in order of preference.
  20 #       By default, only try to emulate the native platform.  See the
  21 #       _EMUL_PREFER.* table below for additional preferences for various
  22 #       platforms.
  23 #
  24 # Package-settable variables:
  25 #
  26 # EMUL_PLATFORMS
  27 #       List of "${EMUL_OPSYS}-${EMUL_ARCH}" binary emulations supported
  28 #       by the package.  This should be set prior to the inclusion of
  29 #       bsd.prefs.mk.
  30 #
  31 #       Default value: undefined
  32 #
  33 # Variables defined by this file:
  34 #
  35 # EMUL_ARCH
  36 #       The machine architecture being emulated, e.g. i386.  If the
  37 #       package isn't supported on this machine, then its value is
  38 #       "none".
  39 #
  40 # EMUL_OPSYS
  41 #       The operating system being emulated, e.g. linux.  If the
  42 #       package isn't supported on this machine, then its value is
  43 #       "none".
  44 #
  45 # EMUL_IS_NATIVE
  46 #       Whether or not the operating system being emulated matches the
  47 #       native operating system.  It is either defined or undefined.
