+/*
+ * Variables can efficiently store primitive types and can hold references to
+ * objects. Objects can store properties which are themselves variables.
+ * Properties can be primitive data types, other objects or functions.
+ * Properties are indexed by a character name. A variable may store one of
+ * the following types:
+ *
+ * string, integer, integer-64bit, C function, C function with string args,
+ * Javascript function, Floating point number, boolean value, Undefined
+ * value and the Null value.
+ *
+ * Variables have names while objects may be referenced by multiple variables.
+ * Objects use reference counting for garbage collection.
+ *
+ * This module is not thread safe for performance and compactness. It relies
+ * on upper modules to provide thread synchronization as required. The API
+ * provides primitives to get variable/object references or to get copies of
+ * variables which will help minimize required lock times.
