#### Hello ... this is a heavily hacked script by Luuk 
#### instead of printing the result it makes a nice gif
#### when you want to look at the code ... beware of the 
#### ugliest code ever seen .... but it works ...
#### and that's sometimes the only thing you want ... isn't it ...
#### as the original script ... Hope you like it

## if you want the seconds behind the bar printed or not ...
## or only the one where the bar is too big for the graph ...
## look at line 535 of this program and below ...
## look in sub calculate for allmost all hard/soft settings :-)

# a little program to generate a table of results
# just read all the RUN-*.log files and format them nicely
