I just wandering: Suppose one wants to score three words and
s/he wants to be sure that this three words are exist in the text.
The only way that I can see is:
* 1^1 word1
* 1^1 word2
* 1^1 word3
| /do/something/with $=
Now, we can be sure that $= >= 3 and every word appearances
at least one time i.e. if $= == 5 then the word1 could not
appearance 3 times.
There is a big deficiency in this recipe - procmail pass twice
on the data. Any idea?
