-# expgen.sh
-#
-# Export Generator
-#
-# This is a script to generate the a list of exports that is required
-# for Windows DLL creation.
-#
-# It processed the mps header files and produces a .DEF file that is
-# suitable for use with the linker when producing a DLL file on Windows.
-#
-# When run, this script produces the following output files:
-# expgen - a plain text list of functions declared in the header files.
-# w3gen.def - a .def file suitable for use in the linker stage when
-# building a Windows .DLL.
-#
-# Procedure for rebuilding a new w3gen.def
-#
-# This procedure should be carried out when the contents of w3gen.def
-# would change. This is a bit tricky to say exactly when, but certainly
-# when:
-# a) new functions are declared in public header files.
-# b) different header files are released to a client.
-#
-# Procedure:
-#
-# 0) Note: This procedure worked with gcc 3.3 "gcc (GCC) 3.3 20030304
-# (Apple Computer, Inc. build 1495)", running on Mac OS X 10.3.
-# However, at 2005-10-12, with gcc 4.0 "gcc version 4.0.0 (Apple
-# Computer, Inc. build 5026)", running on Mac OS X 10.4.2, it did not
-# work. Invoking "gcc -fdump-translation-unit spong.h" did not produce
-# a "spong.h.tu" file.
-#
-# 1) Ensure that the sources for w3gen.def are submitted. w3gen.def
-# must be built from versioned sources.
-# The sources are:
-# expgen.sh
-# w3build.bat
-# all the headers that get included.
-# For safety's sake better to ensure that no files are open:
-# p4 opened ...
-# should say '... - file(s) not opened on this client.'
-#
-# 2) Open w3gen.def for edit (making it writable)
-# p4 open w3gen.def
-#
-# 3) Run this script.
-# sh expgen.sh
-# There should be no output when successful.
-#
-# 4) Eyeball the diff.
-# p4 diff ...
-# Check the that resulting diff is sane. For most changes it should
-# just consist of a new symbol being included (plus some Header related
-# junk).
-#
-# 5) Submit the change.
-# p4 submit ...
-#
-#
-# Design
-#
-# The script works by using the -fdump-translation-unit option of gcc.
-# This produces a more easily parseable rendering of the header files.
-# A fairly simple awk script is used to process the output.
-#
-#
-# Dependencies
-#
-# This script currently depends fairly heavily on being run in a
-# Unix-like environment with access to the GNU compiler.
-#
-# It's also fairly sensitive to changes in the undocumented format
-# produced by gcc -fdump-translation-unit. Hopefully it is fairly easy
-# to adapt to changes in this output.
-#
-# Assumes it can freely write to the files "fun", "name-s".
-#
-#
-# Awk crash course
-#
-# Awk processes files line-by-line, thus the entire script is executed
-# for each line of the input file (more complex awk scripts can control
-# this using "next" and "getline" and so on).
-#
-# In awk $exp identifies a field within the line. $1 is the first
-# field, $2 is the second and so on. $0 is the whole line. By default
-# fields are separated by whitespace.
-#
-# string ~ RE is a matching expression and evaulated to true iff the
-# string is matched by the regular expression.

-; This is a list of the external MPS functions (those a client

-; This list is for the w3i3mv platform.
-;
-; If you wish to link with the MPS library AND re-export these
-; functions from it (for example: so that other DLLs linked with
-; your binary will also be able to make direct MPS calls), then
-; you can specify:
-; /def:
-; to the MSVC LINK.EXE when you link your binary.
-;
-; This file was initially generated by !Header: //info.ravenbrook.com/project/mps/branch/2004-12-15/dll/code/expgen.sh#4 !
-; And since then has been hand-edited. (But the result should be
-; identical (apart from ordering) to what expgen.sh would produce,
-; were it run on these sources. See MPS job001935.)
