Sleep is the Scripting Language for Enhancing Existing Programs. Sleep is a small scripting language with perl-like syntax implemented in Java.

The attribute that makes Sleep different is it allows an application developer to develop "bridges". A bridge is a very simple class that implements a Function, Predicate, Loadable, or Operator interface (or any combination thereof). Sleep is easily extendable to make an application's features available to end-user scripters.
