# This project adds a Lua Proxy DLL on Windows
# By an unfortunate choice in the popular LuaBinaries distribution, there are two names for the Lua DLL on Windows: lua51.dll and lua5.1.dll.
# Some binary Lua packages are built for one, the others for the other. Messy!
# In order to support both package flavors, we create a "proxy DLL":
# Basically the lua5.1.dll has its PE Exports section manipulated so that it points each exported function to its lua51.dll implementation.
# Effectively, this forwards all calls from lua5.1.dll to lua51.dll without any performance costs (the forwarding is done in the Windows PE loader on app start).
# This project creates the proxy DLL by using a specially crafted .DEF file that is used to link the Proxy DLL.
# Note that it has been tested only on MSVC, it might not work with other compilers.
# The initial implementation was taken from http://lua-users.org/wiki/LuaProxyDllFour , but adapted to MSVC
