+# Security holding package
+
+This package name is not currently in use, but was formerly occupied
+by another package. To avoid malicious use, npm is hanging on to the
+package name, but loosely, and we'll probably give it to you if you
+want it.
+
+You may adopt this package by contacting support@npmjs.com and
+requesting the name.
