Here is a famine that is a merge of the features of my previous
one and the one from unc!mp.

#! /bin/sh

: famine is a widget for empire.
: given a census report from empire
: it prints the minimum amount of
: food necessary for each sector and
: the difference between what is there
: and should be there. sectors that are
: below the minimum are flagged with
: an asterisk '*', sectors that are not
: self sustaining are flagged with a
: tilde '~'.

: these magic numbers were gleaned
: from "info food" and "info innards",
: they may need to be changed.
eatrate=0.048
fcrate=1.666
