it is actually not that bad. tcl is a programming language like many others
and has very similar features. the most difficult thing typically is
to understand
the somewhat quirky behavior of using the square brackets ([ ]). which is
more-or-less the same as backward quotes (` `) in shell scripts.

all you want to do for now, is just to modify a given script to suit your needs.
that requires much less knowledge than writing something new.

cheers,
    axel.

However, since I am not very familiar with the tcl language, it is not clear to me where the place the following command [format "Time: %f ps" $timestepvariable] suggested by Axel in the display_time_bar.tcl script to show the value of the current time in the progress Bar.
