-/* This is an example for the C/C++->Pure interface. It implements a silly

-   Please note that the interface to the interpreter, as provided by the
-   public runtime API, is rather minimalistic right now. In particular, the

+   Compile this with 'gcc -o poor poor.c -lpure', and run the resulting
+   executable as './poor [args ...]'. You can use the same command line
+   arguments as with the real Pure interpreter, including any Pure scripts to
+   be loaded at startup. Input is line-oriented, so you can't continue
+   definitions across lines, but in return you don't have to terminate each
+   line with a ';' either, the eval() function already takes care of that.
