#
# 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 libcrypto.num and libssl.num,
# The format of these files is:
#
# routine-name nnnn vers info
#
# The "nnnn" and "vers" fields are the numeric id and version for the symbol
# respectively. 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 variants 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, or the symbol is implemented differently (see
# EXPORT_VAR_AS_FUNCTION). This script assumes renaming of symbols is found
# in the file crypto/symhacks.h.
# The semantics for the platforms is that every item is checked against the
# environment. For the negative items ("!FOO"), if any of them is false
# (i.e. "FOO" is true) in the environment, the corresponding symbol can't be
# used. For the positive itms, if all of them are false in the environment,
# the corresponding symbol can't be used. Any combination of positive and
# negative items are possible, and of course leave room for some redundancy.
# - "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.
