+/*
+ Enable easy piping under Windows(TM) command line.
+
+ We use the 'devenv'(TM) method, which means we have two binary files:
+
+  openscad.com, with IMAGE_SUBSYSTEM_WINDOWS_CUI flag set
+  openscad.exe, with IMAGE_SUBSYSTEM_WINDOWS_GUI flag set
+
+ The .com version is a 'wrapper' for the .exe version. If you call
+ 'openscad' with no extension from a script or shell, the .com version
+ is prioritized by the OS and feeds the GUI stdout to the console. We use
+ pure C to minimize binary size when cross-compiling (~10kbytes). See Also:
