Comment(by jorix):

 Features proposed in the patch for use of the Closure Compiler:

  * Use any OpenLayers configuration (*.cfg)
  * Show where there have been compilation errors: source file and line
 number (source code is used, not jsmin)
  * Maximize the checks but discard massive warnings (9676 warnings
 reported using "- warning_level VERBOSE"!)
  * Ensure the verification of undeclared variables (distractions make
 these variables as global)
  * Use externs to declare names of other products, commercial maps,
 Proj4js ...
  * Use SIMPLE_OPTIMIZATIONS, which compresses the code by 20%
 (ADVANCED_OPTIMIZATIONS requires a study of the pros and cons)
  * Launch the Java compiler from phython (discard the use of the Service
 API. To call the compiler uses material from "Closure Library")
