Hello everybody!

I’m happy to announce jsc, the Javascript Compiler.

With jsc you can compile your JavaScript code throught Google Closure  
Compiler REST service[1].

== Install

Run:

[sudo] gem install jsc

or get source from [GitHub - sub/jsc: Ruby API to Google Closure Compiler Web service](http://github.com/sub/jsc)

== Samples of usage

Get compiled code, if no errors are found:  
jsc compiled\_code.js

Just check for errors:  
jsc errors.js -e

Run jsc --help for more info about allowed options.

== Flymake

For GNU Emacs users, jsc provides a flymake[2] compatible output. So you  
can use  
jsc+flymake to have a syntax check tool running in the background while  
editing  
javascript files:
