Hi Marcus,

in order to copy a file if target file does not exist, you'd need the 'make' 
rule:

   make dst : src : copy ;
   actions copy
   {
       cp $(>) $(<)
   }

to remove a specific file (unconditionally), write:

   notfile remove_them : remove : file ;
   actions remove
   {
       rm $(>)
   }

both approaches are not very portable (they use specific tool names), but 
that's all we have at the moment. Can you tell why you're looking for such 
actions? Maybe, the 'install' rule together with the --clean, option will be 
enough?
