+\fBnpm-link\fR \- Symlink a package folder
+.SH SYNOPSIS
+.P
+.RS 2
+.nf
+npm\.commands\.link(callback)
+npm\.commands\.link(packages, callback)
+.fi
+.RE
+.SH DESCRIPTION
+.P
+Package linking is a two\-step process\.
+.P
+Without parameters, link will create a globally\-installed
+symbolic link from \fBprefix/package\-name\fP to the current folder\.
+.P
+With a parameters, link will create a symlink from the local \fBnode_modules\fP
+folder to the global symlink\.
+.P
+When creating tarballs for \fBnpm publish\fP, the linked packages are
+"snapshotted" to their current state by resolving the symbolic links\.
+.P
+This is
+handy for installing your own stuff, so that you can work on it and test it
+iteratively without having to continually rebuild\.
+.P
+For example:
+.P
+.RS 2
+.nf
+npm\.commands\.link(cb)           # creates global link from the cwd
+                                # (say redis package)
+npm\.commands\.link('redis', cb)  # link\-install the package
+.fi
+.RE
+.P
+Now, any changes to the redis package will be reflected in
+the package in the current working directory
