-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.

 '''
-This is a helper script. See emcc.
+This is a helper script. It runs make for you, setting
+the environment variables to use emcc and so forth. Usage:
+
+  emmake make [FLAGS]
+
+Not that if you ran configure with emconfigure, then
+the environment variables have already been detected
+and set. This script is useful if you have no configure
+step, and your Makefile uses the environment vars
+directly.
+
+The difference between this and emconfigure is that
+emconfigure runs compilation into native code, so
+that configure tests pass. emmake uses Emscripten to
+generate JavaScript.
