#
# generate a .def file
#
# It does this by parsing the header files and looking for the
# prototyped functions: it then prunes the output.
#
# Intermediary files are created, call libeay.num and ssleay.num,...
# Previously, they had the following format:
#
# routine-name nnnn
#
# But that isn't enough for a number of reasons, the first on being that
# this format is (needlessly) very Win32-centric, and even then...
# One of the biggest problems is that there's no information about what
# routines should actually be used, which varies with what crypto algorithms
# are disabled. Also, some operating systems (for example VMS with VAX C)
# need to keep track of the global variables as well as the functions.
#
# So, a remake of this script is done so as to include information on the
# kind of symbol it is (function or variable) and what algorithms they're
# part of. This will allow easy translating to .def files or the corresponding
# file in other operating systems (a .opt file for VMS, possibly with a .mar
# file).
#
# The format now becomes:
#
# routine-name nnnn info
#
# and the "info" part is actually a colon-separated string of fields with
# the following meaning:
#
# existence:platform:kind:algorithms
#
# - "existence" can be "EXIST" or "NOEXIST" depending on if the symbol is
# found somewhere in the source,
# - "platforms" is empty if it exists on all platforms, otherwise it contains
# comma-separated list of the platform, just as they are if the symbol exists
# for those platforms, or prepended with a "!" if not. This helps resolve
# symbol name replacements for platforms where the names are too long for the
# compiler or linker, or if the systems is case insensitive and there is a
# clash. This script assumes those redefinitions are place in the file
# crypto/symhacks.h.
# The semantics for the platforms list is a bit complicated. The rule of
# thumb is that the list is exclusive, but it seems to mean different things.
# So, if the list is all negatives (like "!VMS,!WIN16"), the symbol exists
# on all platforms except those listed. If the list is all positives (like
# "VMS,WIN16"), the symbol exists only on those platforms and nowhere else.
# The combination of positives and negatives will act as if the positives
# weren't there.
# - "kind" is "FUNCTION" or "VARIABLE". The meaning of that is obvious.
# - "algorithms" is a comma-separated list of algorithm names. This helps
# exclude symbols that are part of an algorithm that some user wants to
# exclude.
