-6. Compiling CloudSim: using Ant
---------------------------------
-
-This release contains a simple buildfile for compiling CloudSim classes.
-You need to have ant installed (http://ant.apache.org/).
-Ant can be used in both Windows and Unix/Linux environment.
-
-Usage:
-
-  * Being in the CloudSim root directory (cloudsim/), type 'ant' to compile all 
-    cloudsim source files, put them into the classes/ directory and to create 
-    a cloudsim-new.jar file in the jars/ directory
-    
-  * Being in the CloudSim root directory (cloudsim/), type 'ant clean' to delete 
-    all the compiled classes and the classes/ directory itself. The generated 
-    cloudsim-new.jar is not deleted.
-
-Note:
-
-  * You need to set up PATH for ant in Windows and/or Unix.
