Pizza tools

Dear all,

I want to use Pizza tools, but i don’t understand what syntax should be used. I tried this syntax in terminal (ubuntu) but i got some error: python gnu.py g("plot ‘text.txt’ using 1:2 with lines ")

Please help me.
Thanks

If you download Pizza.py from its web site: http://pizza.sandia.gov
there are doc pages and a dir of example scripts.
