+npm-prune(1) -- Remove extraneous packages
+==========================================
+
+## SYNOPSIS
+
+ npm prune [<name> [<name ...]]
+ npm prune [<name> [<name ...]] [--production]
+
+## DESCRIPTION
+
+This command removes "extraneous" packages. If a package name is
+provided, then only packages matching one of the supplied names are
+removed.
+
+Extraneous packages are packages that are not listed on the parent
+package's dependencies list.
+
+If the `--production` flag is specified or the `NODE_ENV` environment
+variable is set to `production`, this command will remove the packages
+specified in your `devDependencies`. Setting `--production=false` will
+negate `NODE_ENV` being set to `production`.
