Look at the quickbook toolset.  It has some
features that you don't need, but the important
part is to
a) define a feature to pass the tool executable
b) Create a custom generator class that adds
   a dependency on your tool.
c) use toolset.flags to convert the feature to
   a VARIABLE in the updating action.
