+"""passlib.hash - proxy object mapping hash scheme names -> handlers
+
+Note
+====
+This module does not actually contain any hashes. This file
+is a stub that replaces itself with a proxy object.
+
+This proxy object (passlib.registry._PasslibRegistryProxy)
+handles lazy-loading hashes as they are requested.
+
+The actual implementation of the various hashes is store elsewhere,
+mainly in the submodules of the ``passlib.handlers`` package.
+"""

+# NOTE: could support 'non-lazy' version which just imports
+#       all schemes known to list_crypt_handlers()
