How do we invoke the wxPython UI as a stand-alone process?
For the Tcl/Tk UI, G_gui() essentially does:
fp = popen("$GRASS_WISH", "w");
fprintf(fp, "source $env(GISBASE)/etc/gui.tcl\n");
generate_tcl(fp);
We need an equivalent sequence for wxPython, e.g.:
fp = popen("python", "w");
fprintf(fp, /* WHAT GOES HERE ? */);
generate_xml(fp);
[There isn't a generate_xml() function at present; it's called
G_usage_xml() and has stdout hardcoded, so that needs to be
re-factored.]
Currently, menuform.py if run standalone will accept one argument, the
grass command, and will call it on its own to get back the
--xml-description. So an execve() should be enough, I think.
However, menuform.py should be stripped of most dependencies, such as
the cmd window.
