26 Usage: Initialize with pipe-filename-base, client class to receive
27 messages, and callback-function that will be called with the messages.
28 When you want to send, use "send()".
29 This class encapsulates all the dirty communication and thus provides
30 a clean string interface.

36 This is one of the small things that would have been a lot
37 cleaner with a Signal/Slot thing.
