.SH DESCRIPTION |
|||
|
|||
Node is a set of libraries for javascript which allows |
|||
it to be used outside of the browser. It is primarily |
|||
focused on creating simple, easy to build network clients |
|||
and servers. |
|||
|
|||
|
|||
.SH OPTIONS |

|||
-v, --version print node's version |
|||
|
|||
-e, --eval script evaluate script |
|||
|
|||
-p, --print print result of --eval |
|||
|
|||
-i, --interactive always enter the REPL even if stdin |
|||
