When an alias is created, a directory named <alias>_bin is also created in the alias directory, and a symlink pointing to the target's node binary is created within that directory. This allows you to, for example, make that alias's node the default node binary for all users, by placing a symlink to the alias's symlink in, say, /usr/bin. This is most handy for ensuring that node scripts which must be run as root, such as init scripts that change their uids, will have access to a node binary. |

Node Version Manager
Installation
First you'll need to make sure your system has a c++ compiler. For OSX, XCode will work, for Ubuntu, the build-essential and libssl-dev packages work.
To install create a folder somewhere in your filesystem with the "nvm.sh" file inside it. I put mine in a folder called ".nvm".
Or if you have git installed, then just clone it:
git clone git://github.com/creationix/nvm.git ~/.nvm
To activate nvm, you need to source it from your bash shell
. ~/.nvm/nvm.sh
I always add this line to my ~/.bashrc or ~/.profile file to have it automatically sources upon login.
Often I also put in a line to use a specific version of node.
Usage
To download, compile, and install the v0.4.1 release of node, do this:
nvm install v0.4.1
And then in any new shell just use the installed version:
nvm use v0.4.1
If you want to see what versions are available:
nvm ls
To restore your PATH, you can deactivate it.
nvm deactivate
To set a default Node version to be used in any new shell, use the alias 'default':
nvm alias default v0.4.1
