36 # version.pl
38 # Parse the NASM version file and produce appropriate macros
40 # The NASM version number is assumed to consist of:
42 # <major>.<minor>[.<subminor>][pl<patchlevel>]]<tail>
44 # ... where <tail> is not necessarily numeric, but if it is of the form
45 # -<digits> it is assumed to be a snapshot release.
47 # This defines the following macros:
49 # version.h:
50 # NASM_MAJOR_VER
51 # NASM_MINOR_VER
52 # NASM_SUBMINOR_VER -- this is zero if no subminor
53 # NASM_PATCHLEVEL_VER -- this is zero is no patchlevel
54 # NASM_SNAPSHOT -- if snapshot
55 # NASM_VERSION_ID -- version number encoded
56 # NASM_VER -- whole version number as a string
58 # version.mac:
59 # __?NASM_MAJOR?__
60 # __?NASM_MINOR?__
61 # __?NASM_SUBMINOR?__
62 # __?NASM_PATCHLEVEL?__
63 # __?NASM_SNAPSHOT?__
64 # __?NASM_VERSION_ID?__
65 # __?NASM_VER?__
