Well, this is certainly correct advice, but could anybody point to how to
make this programatically? I guess the whole change would be
 cp cash-flow.scm cash-flow-monthly.scm
 vim cash-flow-monthly.scm # add "/12" somewhere
 vim ?/report.scm

Am I right? If so, where should I add that "/12"?

 Thanks for any advice,

We have a criminal jury system which is superior to any in the
world; and its efficiency is only marred by the difficulty of
finding twelve men every day who don't know anything and can't
