+/* Setuptools Script Launcher for Windows
+
+ This is a stub executable for Windows that functions somewhat like
+ Effbot's "exemaker", in that it runs a script with the same name but
+ a .py extension, using information from a #! line. It differs in that
+ it spawns the actual Python executable, rather than attempting to
+ hook into the Python DLL. This means that the script will run with
+ sys.executable set to the Python executable, where exemaker ends up with
+ sys.executable pointing to itself. (Which means it won't work if you try
+ to run another Python process using sys.executable.)
+
+ To build/rebuild with mingw32, do this in the setuptools project directory:
+
+ gcc -DGUI=0 -mno-cygwin -O -s -o setuptools/cli.exe launcher.c
+ gcc -DGUI=1 -mwindows -mno-cygwin -O -s -o setuptools/gui.exe launcher.c
+
+ To build for Windows RT, install both Visual Studio Express for Windows 8
+ and for Windows Desktop (both freeware), create "win32" application using
+ "Windows Desktop" version, create new "ARM" target via
+ "Configuration Manager" menu and modify ".vcxproj" file by adding
+ "<WindowsSDKDesktopARMSupport>true</WindowsSDKDesktopARMSupport>" tag
+ as child of "PropertyGroup" tags that has "Debug|ARM" and "Release|ARM"
+ properties.
+
+ It links to msvcrt.dll, but this shouldn't be a problem since it doesn't
+ actually run Python in the same process. Note that using 'exec' instead
+ of 'spawn' doesn't work, because on Windows this leads to the Python
+ executable running in the *background*, attached to the same console
+ window, meaning you get a command prompt back *before* Python even finishes
+ starting. So, we have to use spawnv() and wait for Python to exit before
+ continuing. :(
