 Usage:
   revvy <listening_port> <mapping1> [<mapping2>] [<mapping3>]
-  revvy (version | --version)
 
 Note:
-    - a mapping is: "/path|http://localhost:4200"
+    - a mapping is: "<path>:<host>:<port>", i.e. "/api:localhost:8080"
+    - if the request path starts with "<path>", then the request is routed to "<host>:<port>"
+    - mappings are evaluated in order, so put your 'catch-all' (i.e. "/:localhost:4200") for last
+
+Example:
+    - develop a fullstack SpringBoot (context-root=/api) + Angular application on localhost:
+        revvy 9999 /api:localhost:8080 /:localhost:4200
+        and then open localhost:9999 on your browser
+        (eventually adjust your Angular api baseurl to point at localhost:9999)
