how to suppress wxMaxima greeting text



dear group,

I am preparing wxMaxima worksheets *.wxm for my students.
Opening such a sheet via the Open Command in wxMaxima shows some 'lines of greeting':
version number, credits etc. But I would like to see only my text with exercises, problems
etc of the worksheet.

Q: (how) is it possible to realise that? 
   is there a option 'suppress greeting text'?
