The procedure to run tcltkgrass/Linux

Hi,
     I just compiled the tcltkgrass on Linux and played with it for a while.
But I am not sure what the proper procedure is to run tcltkgrass. Since there
is no documentation yet, I can only guess. Here is how I run it. Please
correct me if I am wrong.
      1) inside X Window, start the shell script /script/tcltkgrass. A logo
shows up, then select a data set.
      2) the tcltkgrass window show up, but I get the % wish sign in the back
(not sure whether it is correct).
      3) at the %, type source tcltkgrass.tcl to invoke the menu (I think
I may have missed something, otherwise, why do I have to invoke the menu
manually, any idea?)
      4) then everything works fine.
    Suggestions or comments are appreciated.
