+class commandmanager(object):
+
+    """
+    Use this instead of @hook.command for your command methods. (@commandmanager(things...))
+
+    It will take care of the following things:
+    - Basic permission check. The default permission is utils.<cmd_name>
+    - Sender type check. You can pass whether the sender must be a player, a consolesender, or both. (see sender_limit below)
+    - Minimum and maximum args. Works with checkargs from helpers.py.
+    - A '/<cmd> help' message containing the description, usage and aliases of the command.
+
+    Information about some arguments:
+    - f:                The method. Don't bother with that.
+    - cmd_name:         The command you type in chat.
+    - usage:            For example "<player> <other_player" and is part of the help message.
+    - description:      A brief description of what the command does. (also part of the help message)
+    - aliases:          A list of aliases for the command
+    - permission:       The basic permission for the command. Defaults to utils.<cmd>
+    - sender_limit:     Defines what sendertype can use the command. Leave blank for console & player, 0 for player only, 1 for console only.
+    - min_args:         The least arguments for the command.
+    - max_args:         You guessed it right. Defaults to infinity (-1).
+
+    *** DISCLAIMER ***
+
+    Your command function must take three arguments: sender, handler, args.
+    Where handler is the instance of this class. You can for example return help_message(sender), get the given arguments etc.
+
+    Your function must also not return a boolean like before, but a String instead. The string returned will be sent to the player (&-codes supported).
+    Use None or "" for no message.
+
+    Feel free to edit or give suggestions (but don't break existing commands)
