 /**
  * @file Script.hh
  * A thin wrapper over Lua.  This is not meant as a complicated binding
- * package between C++ and Lua.  It does not try to make the boundary
- * invisible.  It does not hide the concept of the Lua stack, but rather
+ * package between C++ and Lua.  It is not meant to obscure the division
+ * between C++ and Lua but rather to clarify it and make it more
+ * manageable.  It does not hide the concept of the Lua stack, but rather
  * provides that mechanism with a certain level of abstraction while also
  * providing a cleaner, more consistent API.
