+# Notes about slapd for Windows
+# =============================
+# slapd.exe must export all of its global symbols, just like a DLL.
+# The purpose of this is to allow dynamic modules (dynamic backends
+# or external dynamic modules) to bind with the symbols at run-time.
+#
+# Exporting symbols from an .EXE is a bit tricky and involves multiple
+# steps. First a .DEF file must be generated. The .DEF file indicates
+# the set of symbols that are to be exported. Many times, it's possible
+# to manually create this file with an editor. However, with slapd,
+# we want to export EVERY global symbol that it knows about (NOT including
+# symbols that are imported from other DLLs). The set of symbols to
+# export INCLUDES symbols from all static libraries that slapd gets
+# linked with, e.g. avl, ldbm, ldif, lunicode, lutil, etc. This list
+# will also include liblber and libldap_r if they were built as static
+# libraries. ALSO included will be symbols from other STATIC libraries
+# outside the domain of the OpenLDAP source tree, e.g. regex, ltdl,
+# crypto, ssl, sasl, etc. (If these libraries are dynamic, we won't want
+# to include their symbols in the list). The correct set of symbols
+# CAN be determined at build time. The slapd.def target automatically
+# determines the correct set of symbols and generates the slapd.def file.
+#
+# The slapd.def file, serving multiple purposes, will:
+#
+# 1) be used to generate libslapd.a, the import library for slapd.exe.
+#
+# 2) be used to generate the symdummy.c file.
+#
+# 3) be used to help create slapd.exp, the binary-formated slapd export file.
+#
+# The import library is used by dynamic modules at link time. With this
+# library, dynamic modules indicate to the linker that it will resolve
+# these symbols from the slapd.exe binary at run-time. Of course, whenever
+# a module imports dynamic symbols, those symbols should be marked with
+# the __declspec(dllimport) directive in the header files that the dynamic
+# modules build with. In OpenLDAP, this is handled automatically in the
+# header files. (See ldap_cdefs.h for an explanation). Writers of
+# dynamic backend modules should keep in mind that slapd.exe might export
+# other global symbols that are not part of OpenLDAP (e.g. regex, ltdl,
+# crypto, ssl, sasl, etc.) When a writer actually uses (i.e. imports) these
+# symbols, he must verify that the header files from these external packages
+# include a mechanism to mark imported symbols with the __declspec(dllimport)
+# directive. Whether or not such a mechanism exists, the writer must be
+# able to include these directives appropriately when their symbols are
+# being imported from slapd.exe. The directive is not completely necessary
+# for functions, but it is required for variables.
+#
+# The symdummy.c file basically references EVERY symbol available to slapd.exe,
+# including symbols that slapd.exe never actually refereneced. The file
+# is compiled and included at link time. Without this object file, slapd.exe
+# would NOT export symbols that it never referenced. The reason that these
+# symbols must still be exported is because a dynamic module may want to
+# use a symbol even if it had not been referenced by slapd.exe.
+#
+
+#
+# slapd.def REALLY depends upon all slapd objects and all static libraries
+# included in $(LIBS), including static libraries outside of OpenLDAP.
+# When slapd.def is built, the absolute paths to all static libraries
+# (both inside and outside of OpenLDAP) are generated. We don't have
+# any way to include this generated list as a dependency of slapd.def (sigh).
+# Thus, we do the best we can by depending on version.o, which depends
+# on its own very long list of dependencies.
