@echo off
REM Build script for FastSMRW (FastPlay-style direct cl/lib build, no CMake).
REM
REM Usage:
REM   build.bat              Release build (fastsm_core.lib + FastSMRW.exe)
REM   build.bat debug        Debug build (/MTd, /Zi, symbols)
REM   build.bat test         Build + run the unit tests
REM   build.bat clean        Remove the build\ tree
REM   (args combine, e.g. "build.bat debug test")
REM
REM Convention: keep source file basenames unique within a target (objs are
REM flattened into one dir per target).
