"""Generates the gtest.def file to build Google Test as a DLL on Windows.
SYNOPSIS
Put diagnostic messages from building gtest_dll_test_.exe into
BUILD_RESULTS_FILE and invoke
generate_gtest_def.py <BUILD_RESULTS_FILE
Reads output of VC++ linker and re-generates the src/gtest.def file
required for building gtest as a DLL.
Use this script if you modify Google Test's source code and Visual
Studio linker starts complaining about unresolved external symbols.
You may have to repeate the build/re-generate cycle several times
because VC++ limits the number of unresolved external symbols it can
report at a time.
EXAMPLES
scons\scons.py | scripts\generate_gtest_def.py
This tool is experimental. Please report any problems to
googletestframework@googlegroups.com. You can read
http://code.google.com/p/googletest/wiki/GoogleTestAdvancedGuide for more
information.
