 Bounce
 ====
 
-Reloads node upon changes to source files. 
+Reloads process upon changes to source files and exceptions. 
 Great for development.
 
 How?
 ----
 
-Runs node as child process whilst watching JS file in the current directory and below for changes.
-If a change is detected, the node child process is restarted. It also looks for new files JS every 10s.
+Runs node as child process whilst watching specified files changes.
+If a change is detected, the child process is restarted.
 
 All STDOUT AND STDERR should be piped back to the console, so it shouldn't look any different.

 Usage
 ----
 
-simply replace 'node' for 'bounce'. E.g.
-
-bounce lib/server.js
+bounce -w [-r] [-g] 'command_to_run -a -b arg1 arg2' 
 
+-w: watch paths, comma separated. If using globs (*) then must be wrapped in quotes, e.g. 'lib/*.*' 
+-r: respawn on child process exit
+-g: growl notify on child process exit (needs growlnotify)
+-h: show this usage
 
 Running Tests
 ----
 
-* bin/bounce test/test.js
+* bin/bounce -r -g -w "node test/test.js"
 
   Changes to test.js and watch/file.js should cause the counter to restart.
 
-* bin/bounce test/error.js
+* bin/bounce -w "node test/error.js"
   Should throw an error and exit immediately
 
-Tested on Ubuntu/OSX on Node 0.2.0 and 0.1.104
+Tested on Ubuntu/OSX on Node 0.2.3
 
 Todo
 ----
 
-* how to handle watching different directories than CWD ?
+* npm
