   5 # Parse the NASM version file and produce appropriate macros
   6 #
   7 # The NASM version number is assumed to consist of:
   8 #
   9 # <major>.<minor>[.<subminor>][pl<patchlevel>]]<tail>
  10 #
  11 # ... where <tail> is not necessarily numeric, but if it is of the form
  12 # -<digits> it is assumed to be a snapshot release.
  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_PATCHLEVEL_VER   -- this is zero is no patchlevel
  21 # NASM_SNAPSHOT         -- if snapshot
  22 # NASM_VERSION_ID       -- version number encoded
  23 # NASM_VER              -- whole version number as a string
  24 #
  25 # version.mac:
  26 # __NASM_MAJOR__
  27 # __NASM_MINOR__
  28 # __NASM_SUBMINOR__
  29 # __NASM_PATCHLEVEL__
  30 # __NASM_SNAPSHOT__
  31 # __NASM_VERSION_ID__
