-This is a helper script. See emcc.
+This is a helper script. It runs ./configure for you, setting
+the environment variables to use emcc and so forth. Usage:
+
+  emconfigure ./configure [FLAGS]
+
+You can also use this for cmake and other configure-like
+stages. What happens is that all compilations done during
+this command are to native code, not JS, so that configure
+tests will work properly.
