+    // Load an entry point. This is really a convenience function
+    // which combines calls to load() and getSymbol(). However, it
+    // does add some value.
+    //
+    // An entry point has the following format:
+    //
+    // name[,version]:function
+    //
+    // The name of the library is constructed from the given
+    // information. If no version is supplied and the boolean
+    // argument is true, the Ice version (10 * major + minor) is 
+    // used instead.
+    //
+    // For example, consider the following entry point:
+    //  
+    // foo:create 
+    //
+    // This would result in libfoo.so.11 (Unix) and foo11.dll
+    // (Windows), where the Ice version is 1.1.x.
+    //
+    // Now consider this entry point:
+    //
+    // foo,12:create
+    //
+    // The library names in this case are libfoo.so.12 (Unix) and
+    // foo12.dll (Windows).
+    //
+    // On Windows platforms, a 'd' is appended to the version for
+    // debug builds.

+    // Returns 0 if a failure occurred.
