Installation:
    Please install perl-Date-Calc.rpm
    and touch the DATAFILE, e.g.
    touch $HOME/.tmdata

Files:
    Timemachine uses two files: DATAFILE and COMMFILE. 
    DATAFILE=$HOME/.tmdata

    is used to store the information about logins, logouts, comments. 
    (Before the first use of timemachine you should create it by
    touch $HOME/.tmdata)

    In this file you have:
      * 
        extra worktime (doesn't count as regular workday and 
        is marked with  *)
    §+time§ and §-time§  
        are added/subtracted from the worktime
    §Urlaub--§  and §Urlaub+=123§  
        modify the vacation days 
    §Freizeitausgleich§ 
        increases the days for "Freizeitausgleich" and starts 
        a new workday
    "this is not important" 
        is ignored by timemachine, but can be used to grep for
        certain lines with the -g option


    COMMFILE=$HOME/.tmcomment

    is used to save the comment for writing it later to DATAFILE
