+npm-publish(3) -- Publish a package
+===================================
+
+## SYNOPSIS
+
+    npm.commands.publish([packages,] callback)
+
+## DESCRIPTION
+
+Publishes a package to the registry so that it can be installed by name.
+Possible values in the 'packages' array are:
+
+* `<folder>`:
+  A folder containing a package.json file
+
+* `<tarball>`:
+  A url or file path to a gzipped tar archive containing a single folder
+  with a package.json file inside.
+
+If the package array is empty, npm will try to publish something in the
+current working directory.
+
+This command could fails if one of the packages specified already exists in
+the registry.  Overwrites when the "force" environment variable is set.
