        ipp -> the interactive python prompt
        
        An enhanced console for Python.
        Features are:
        - readline support if present
        - completion in the local namespace, eg. type TAB twice at the prompt.
        - logging of input , see command-line options
        - Systemshell escape by the ! , eg !ls
        - Pythonshell commands, starting with a @
        - some of these are  @ls, @pwd, @cd
        - Keeps track of locally defined variables @who, @whos
        - Show documentation with a ? , eg ?list
        - evaluation of a personal config file which can be used to extend
the shell
        - expansion of history lines by a starting '.'
        
        Command line options:
        -i      | execute remaining files and than jump to the prompt
        -l      | logging in standard-log file
        -L file | name a special log file and log into it
        -s      | don't read $HOME/.ipprc
