See also Rbc here.
Which commands should be included?
'''vector:''' needed for graph '''graph:''' curve display widget '''stripchart:''' '''barchart:''' '''busy:''' not needed, because we already have '''tk busy''' '''winop:''' ?
Should there be a special switch to enable compiling and including Rbc?
Should we change Rbc to some other name to prevent name clashes?
Should we export a C-interface?
