To install npm and its documentation, do this:
If you get any complaints, try
sudo make install
man npm or
npm help for more information.
If you want to just install npm, but leave your man folder untouched, you can try this instead:
If you'd prefer to just symlink in the current code so you can hack on it, then you can do this to create a symlink:
./cli.js link .
Any of these will use npm to install itself, like Ouroboros.
A note about password security
In order to publish your packages, you must have your auth info saved into your .npmrc file. If Cipher and Decipher are supported in the "crypto" module, then npm will use them. However, as of node 0.1.92, these functions aren't integrated yet.
You can get around this by doing:
npm install http://github.com/waveto/node-crypto/tarball/v0.0.5
