---url poola:porta -u usernamea -p passa --quota "2;poolb:portb" -u usernameb -p passb
-Will give poola 1/3 of the work and poolb 2/3 of the work.

 Writing configuration files with quotas is likewise supported. To use the above
 quotas in a configuration file they would be specified thus:
 
 "pools" : [
         {
-                "url" : "poola:porta",
-                "user" : "usernamea",
-                "pass" : "passa"
+                "url" : "poolA:portA",
+                "user" : "usernameA",
+                "pass" : "passA"
         },
