From 2064372659156e2637eac4d092321818a30abb41 Mon Sep 17 00:00:00 2001 From: Paul Phillips Date: Mon, 2 Jan 2012 11:48:22 -0800 Subject: Better error reporting regarding main methods. Now notices most things which look like main methods and says something useful if they aren't usable as entry points.
