10
11@brief Implements a local control for a StateMachine based on a Readline class
12
13This template implements all functions which overwrite any function from the
14Readline class needed for a local control of a state machien. Since
15several derivatives of the Readline class implement different kind of
16Readline access, this class can be derived by any of them due to its
17template argument. However, the normal case will be deriving it from
18either Console or Shell.
19
20@tparam T
21   The base class for RemoteControl. Either Readlien or a class
22   deriving from it. This is usually either Console or Shell.
