   6 # Parse the NASM version file and produce appropriate macros
   7 #
   8 # The NASM version number is assumed to consist of:
   9 #
  10 # <major>.<minor>[.<subminor>]<tail>
  11 #
  12 # ... where <tail> is not necessarily numeric.
  13 #
  14 # This defines the following macros:
  15 #
  16 # version.h:
  17 # NASM_MAJOR_VER
  18 # NASM_MINOR_VER
  19 # NASM_SUBMINOR_VER     -- this is zero if no subminor
  20 # NASM_VER              -- whole version number as a string
  21 #
  22 # version.mac:
  23 # __NASM_MAJOR__
  24 # __NASM_MINOR__
  25 # __NASM_SUBMINOR__
  26 # __NASM_VER__
