# generate a .def file
#
# It does this by parsing the header files and looking for the
-# non-prototyped functions.
+# 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.
