18    The imagemap generation also supports this, so you will still be able to point

39  - If no file is entered on the command-line, then the input is taken from  
40    standard input, like all decent *nix programs.  - Implemented folding of empty branches. Many uses of CVS create many
41      branches on the same revision but have no commits on them. This occurs

53    configuration options.    option branch_foldall controls this behavior. See cvsgraph.conf(5) for
54      details. The imagemap is configured to map all branches within the box.
 - It is now possible to draw the connector lines between the boxes thicker  
   by setting thick_lines to something else than 1. Maximum thickness is  
   limited to lines of 11 pixels wide.
