Comment (by eschnett):

 The easiest way to clean up the previous files is to issue a "make clean".
 We have mechanisms in Cactus to enforce a rebuild (rerun the CST stage)
 and to enforce a reconfiguration (rerun configure), but we don't have a
 corresponding mechanism to enforce cleaning.

 I could add code to look for old-style files, and if so, delete the
 Formaline directory, which would then probably lead to a make failure, but
 the next make would succeed. It is difficult to do anything else, because
 make examines the directory structure first and runs commands later, so we
 cannot remove old files before make examines what is there. I'm sure there
 is a trick to do it, but this would require debugging, and would add
 complexity necessary only for the transition.
