2#
3# generate a .def file
4#
5# It does this by parsing the header files and looking for the
6# prototyped functions: it then prunes the output.
7#
8# Intermediary files are created, call libeay.num and ssleay.num,...
9# Previously, they had the following format:
10#
11#	routine-name	nnnn
12#
13# But that isn't enough for a number of reasons, the first on being that
14# this format is (needlessly) very Win32-centric, and even then...
15# One of the biggest problems is that there's no information about what
16# routines should actually be used, which varies with what crypto algorithms
17# are disabled.  Also, some operating systems (for example VMS with VAX C)
18# need to keep track of the global variables as well as the functions.
19#
20# So, a remake of this script is done so as to include information on the
21# kind of symbol it is (function or variable) and what algorithms they're
22# part of.  This will allow easy translating to .def files or the corresponding
23# file in other operating systems (a .opt file for VMS, possibly with a .mar
24# file).
25#
26# The format now becomes:
27#
28#	routine-name	nnnn	info
29#
30# and the "info" part is actually a colon-separated string of fields with
31# the following meaning:
32#
33#	existence:platform:kind:algorithms
34#
35# - "existence" can be "EXIST" or "NOEXIST" depending on if the symbol is
36#   found somewhere in the source,
37# - "platforms" is empty if it exists on all platforms, otherwise it contains
38#   comma-separated list of the platform, just as they are if the symbol exists
39#   for those platforms, or prepended with a "!" if not.  This helps resolve
40#   symbol name replacements for platforms where the names are too long for the
41#   compiler or linker, or if the systems is case insensitive and there is a
42#   clash.  This script assumes those redefinitions are place in the file
43#   crypto/symhacks.h.
44#   The semantics for the platforms list is a bit complicated.  The rule of
45#   thumb is that the list is exclusive, but it seems to mean different things.
46#   So, if the list is all negatives (like "!VMS,!WIN16"), the symbol exists
47#   on all platforms except those listed.  If the list is all positives (like
48#   "VMS,WIN16"), the symbol exists only on those platforms and nowhere else.
49#   The combination of positives and negatives will act as if the positives
50#   weren't there.
51# - "kind" is "FUNCTION" or "VARIABLE".  The meaning of that is obvious.
52# - "algorithms" is a comma-separated list of algorithm names.  This helps
53#   exclude symbols that are part of an algorithm that some user wants to
54#   exclude.
