17 2  62     Diagram Editor
  The graphical image of Feynman diagrams is presented.
  Diagrams with ghost particles  and 4-gluon vertices are not
displayed. They are hidden under the physical ones. 
  The momenta of the outgoing particles are not labeled; in
the case of identical outgoing particles the subsequent
symmetrization is performed automatically.
  If you browse the squared diagrams after usage of the
'Symbolic calculation' function you will see that each of the
diagram is marked by the following labels: "CALC","ZERO",
"Out of memory".They mean that the diagram has been
successfully calculated, gives a zero contribution, or cannot 
be calculated.
  In addition to the standard options of the Diagram Viewer
the following commands are available:
'D'  deletes all diagrams. The deleted diagrams are marked
     by 'DEL' in the bottom r.h. corner of the diagram box;
'R'  restores all deleted diagrams;
'O'  toggles the 'DEL' mark for the selected diagram;
'L'  writes the LaTeX image of all undeleted diagrams to a 
     file. This LaTeX output uses the axodraw.sty package. 
     CompHEP informs you about the file name by a message.
'G'  shows the ghost diagrams hidden under the displayed one.
